Did you say it's under 100g? So, how comfortable is it to wear? What's the world of surprisingly light and compact, ultra-lightweight rainwear that has been actively featured on this site for about two years now, when it was excellent below 300g until just a few years ago? Now, even if you lower than 100g, you will get the above reaction, and this year, as usual, it has evolved as badly as ever.
This trend continues since last year, but as usual, there is an increasing number of products that combine features that suit a variety of activities, not only lighter, but also less likely to get stuffy, more comfortable to wear, and easier to move around. Above all, this year, the number of brands and items that have entered the market has been incredible, even more than last year. From full-scale mountaineering brands to running brands, the biggest feature of this year is that many new products from many brands appear like a star and compete for the sake of their own.
This year, we have checked out a variety of ultra-lightweight rainwear, which is a symbol of the dog-year-old outdoor gear evolution, and have compiled a list of popular models, which are becoming an annual tradition, so we'd like to take a look.
As usual, the basic premise for picking up is whether I wanted it (or bought it without thinking).
However, this time, we have lowered the ultra-lightweight standard to around the early 200g, as the target model has expanded too much under the previous standard of "approximately 300g". In fact, most common mountain climbing rainwear in recent years has achieved considerable performance even at around 300g. As a result, some of the models that were chosen as ultra-lightweight rainwear up until last year will be featured in a special feature on rainwear for full-scale mountain climbing, which will be announced at a later date.

Berghaus Hyper 100 Jacket
Weight★★★ Waterproof★★☆ Breathable★★☆ Comfort★★★ Function★☆☆ Versatility★★☆☆
The most highlight of this season is the "world's lightest 3-layer" waterproof and breathable jacket (according to the brand) that won unmatched gold at two exhibitions, the 2016 OutDoor Show and the ISPO 2017. This is a supreme item, with innovative technology generously introduced by the cutting-edge product development team "MtnHaus Design Team," a British representative comprehensive outdoor brand.
Of course, the editorial department got it at the same time as it was released. The moment I put it on, it was as light as I expected (97g for size M) and the supple feel of the skin, and it was as if nothing had been put on it. The previous model (Vapor Light Hyper Shell Jacket) was lighter at 85g, but since it was 2.5 layers, the lining had to be settled in a vinyl-like texture, which is a major advance. The Hydroshell Elite Pro, an even more innovative material than ever, is the company's lightest and most highly breathable waterproof membrane , and although the specifications have not been announced, it can be expected to be waterproof and comfortable than the previous model.
It's not just lightness that will surprise you. The unique three-dimensional cutting allows for a natural feel around the shoulders and a minimalist design, and the hybrid hood and cuffs are made of rubber and flaps that prevent rain from entering as much as possible, despite being lighter. This game, which is world-class lighter and has the functionality, with the addition of an inner pocket (which was not found in the previous model), is the best recommendation of this year for those who prefer short, high-performance activities, such as trail running or short-term speed hiking.
THE NORTH FACE Strike Trail Hoodie (or Strike Jacket)
Weight★★★ Waterproof★★☆ Breathable★★★ Comfort★★☆ Function★☆☆ Versatility★☆☆☆
The North Face's latest release has been quickly introducing a lineup focused on fast packing and trail running since around last season, and is an ultra-thin, ultra-lightweight waterproof shell that is also designed for use in races. The unique material "HYVENT Flyweight (3 layers)" continues from last year, with reliable specifications, with 20,000mm water resistance and 40,000g breathability. Furthermore, the current model has eliminated the pockets, and reduced the Velcro cuffs, drawstrings for adjusting the hem and hood to the limit, resulting in the company's lightest weight in 110g. Of course, the smooth, three-layer lining is as comfortable as ever and extremely comfortable to wear. The features that are specialized for running, such as clear colors that allow lace bibs to be seen through, are the most attractive features for race-oriented people.
The Strike Jacket introduced last year is also on sale. This is also widely recommended as an ultra-lightweight model that is balanced to make it easy to use not only for running but also for hiking and street wear.
Salomon BONATTI PRO WP JKT
Weight★★☆ Waterproof★★☆ Breathable★★☆ Comfort★★☆ Function★★★ Versatile★☆☆
As expected of a top mountain lace brand, this BONATTI PRO WP JKT was impressive with its detailed features that made you think so. First of all, the suppleness of the outer material, which is not too crisp than necessary, is a great element for running. The gusset placed on the back is a MotionFit structure that pursues freedom of movement, allowing for outstanding ease of movement despite its slim silhouette. It is packed with features that are perfect for running, such as a rubber hood that fits your forehead and prevents water from entering, a reflector that is safe even in the middle of the night, a packable design that can be stored without a stuff sack, and a chest button that prevents fluttering even when the water stopper zipper is open.
Marmot ZERO Penetrate Jacket
Weight★★★ Waterproof★★☆ Breathable★★★ Comfort★★☆ Function★★☆ Versatile★★☆
Recently, Marmot has been making a distinctive UL-style item, with collaborations with Hiker's Depot Tsuchiya, an important figure in ultra-light hiking in Japan, has released a carefully selected ultra-light rainwear that has been significantly upgraded to the previous model ZERO STORM, which was extremely light.
The unique MemBrain Strata is 2.5 layers, but it is surprisingly not as light as it is noticeable. The water pressure resistance of 20,000mm and breathability of 20,000g is also a good success. Above all, the weight has dropped even further from the previous model to 138g, making it one of the best lightest. Personally, the most interesting thing is the hand pocket, which also serves as ventilation. The exquisite ingenuity that functions as a pocket while ensuring breathability can't help but groan "I see." Furthermore, I am impressed by how well-though the hood is designed to fit perfectly despite the lack of adjustment.
This work has changed from the somewhat ordinary construction of the previous model to a unique model with features that only this one can find, and should be useful not only for trail running, but also for lightness-oriented outdoor activities, including fast packing.
Patagonia STORM RACER JACKET
Weight★★☆ Waterproof★★☆ Breathable★★☆ Comfort★★☆ Function★★☆ Versatile★★☆
Patagonia's rain jacket for mountain lace has finally been renewed this year. This model, which was a 2.5-layer model with a slightly inferior weight of 270g, is now completely revamped by a comfortable 3-layer material and a lighter 170g, so it can be said that it has been fully at the forefront.
As always, the company's slim and stress-free three-dimensional cutting is stunning, and the subtle stretch makes it easier to move around. The cuffs are partially elastic, making them both light and fit. The hood can be adjusted to one touch using a cord lock, and a packable design that allows you to store the chest pocket inside out, showing the company's unique personality, not only light, but also overall ease of use.
MONTANE MINIMUS 777 JACKET
Weight★★★ Waterproof★★☆ Breathable★★☆ Comfort★★★ Function★★☆ Versatile★★☆
The lightest waterproof shell of Montain, which won first place overall in a comparison test conducted by the editorial department last year, has not changed since last year. Despite this, he still has a strong ability to overcome. The three layers, which use the lightweight waterproof and breathable membrane "Pertex Shield+", which has been supplied to many brands around the world this year, have a supple and comfortable feel, and keeps the skin smooth and smooth even when sweating, so it won't lose comfort. Not only is the arms swinging when running, but the three-dimensional arms cutting, which ensures high mobility when climbing, is still as amazing as ever. After all, there is no more reliable ally if you use it as equipment for fast packing, trail running, or emergency use, as a way to pursue lightness.
OMM Aether Jacket
Weight★☆☆ Waterproof★☆☆ Breathable★★★ Comfort★★☆ Function★★★ Versatility★★★★
A mountain running jacket that won the 2016 OutDoor Show, renewed in the fall of 2016. Its weight of approximately 200g may not be extremely light, but the jacket's most innovative is its high level of weather resistance, durability and functionality. "eVent" has a long proven track record as a waterproof and breathable membrane that competes with GORE-TEX, and its high breathability makes it seem like the clothing is breathing. The suppleness of the fine fabric, the comfortable three layers of comfortable fit, and the waste-free silhouette made from the calculated three-dimensional cutting inevitably increase your motivation to lace. The hood is easy to fit, cuffs that can be freely adjusted to fit or as a thumb hole, and hem and waist area that are less likely to swell up, making it a unique twist, making it easy to get into, and many people want to buy it despite the high price.
mont-bell versalite jacket
Weight★★☆ Waterproof★★☆ Breathable★☆☆ Comfort★☆☆ Function★☆☆ Versatility★★★
Although it has been a while since its release, it still weighs 168g and is quite competitively light. However, to be honest, I would like to see a slightly better performance improvement in 2017, including breathability, comfort in the lining, the Velcro adjustment mechanism on the left and right hand pockets and the cuffs, but above all, this high cost performance is a special note. It is definitely an easy model for those who are oriented towards light and fast activities such as trail running and fast packing, and who don't want to regret it too much. The figure is also looser than Western models, so it is also recommended for people who fit in it.

Rab FLASHPOINT JACKET
Weight ★★☆ Waterproof ★★☆ Breathability ★★☆ Comfort ★★☆ Functionality ★★☆ Versatility ★★★
This jacket won first place in our comparison tests in 2015 and 2016, combining lightness (185g), weather resistance, functionality, and design at a high level, making it an unquestionably recommended item. Though it's a bit pricey, the the TJAR . The ultra-thin fabric, made with three layers of "Pertex Shield +," now considered the standard for ultra-lightweight membranes, offers a good balance of waterproofness, breathability, and durability, and it held up well in last year's test, even in relatively severe weather. The hood can be precisely adjusted at three points: at the back of the head and on both sides of the face, making it even more suitable for mountain climbing than other models. The slim fit reduces chafing and discomfort even during intense movement.
OUTDOOR RESEARCH HELIUM HYBRID HOODED JACKET
Weight ★☆☆ Waterproof ★☆☆ Breathability ★★☆ Comfort ★★★ Functionality ★★☆ Versatility ★☆☆
Since its inception as a pioneer of ultralight rainwear, the Helium series has continued to expand with the addition of the lightweight "II" and the high-performance "HD." This year, the "HYBRID" has been added to the lineup. While maintaining the lightweight and highly breathable waterproof performance of the highly reliable "Pertex Shield+," the "HYBRID" adds a water-repellent soft shell under the arms, achieving greater mobility and breathability than ever before while maintaining a slim silhouette. While the soft shell isn't strictly waterproof, it doesn't qualify as "rainwear." For those chilly, unpredictable weather conditions when a soft shell isn't a good idea, but carrying rainwear would be too bulky, this is the perfect windproof and waterproof jacket to wear while on the move. Having one on hand expands your options for a variety of situations, making it a useful jacket in many ways
MAMMUT AEROSPEED JACKET
Weight ★☆☆ Waterproof ★★☆ Breathability ★★☆ Comfort ★★☆ Functionality ★★☆ Versatility ★★☆
The previous model (DRYTECH FREEFLIGHT JACKET), which was released last year, has already been revamped with a new name. From actually wearing it, the fabric and cut are almost the same as the previous model, and the stylish silhouette that's characteristic of Mammut, the outer fabric that's not unnecessarily rough, and the overall supple feel of the fabric are very appealing. So what exactly has changed? The main change is the addition of hand pockets on both sides. This has resulted in a slight increase in weight, which may be a drawback for active use such as trail running. However, on the other hand, it could be considered an improvement in usability for gentler activities or as an everyday jacket, so opinions on this point will vary depending on the user's purpose
Karrimor Beaufort 3L Jacket
Weight ★★☆ Waterproof ★☆☆ Breathability ★★★ Comfort ★★☆ Functionality ★☆☆ Versatility ★★☆
This season marks the launch of the "Aerial Series," a lightweight fast-packing model series from British outdoor brand Karrimor. Despite its relatively limited track record in this field, this jacket boasts a water resistance of 15,000mm, breathability of 50,000g, a three-layer construction, and a subtle stretch, all while weighing a respectable 180g. Its specs are comparable to those of the top packs. When I tried it on, I found the body width to be not too tight, and the two hand pockets made it seem more suited to hiking than running. In addition to its excellent breathability, the buttons on the collar prevent flapping even with the front zipper open, providing excellent ventilation
Teton Bros. Breath Jacket
Weight ★☆☆ Waterproof ★☆☆ Breathability ★★★ Comfort ★★★ Functionality ★★☆ Versatility ★★☆
This model has been around since 2016, but its ultra-lightweight rainwear, made with Polartec Neoshell, offers an excellent balance of exceptional breathability, comfort, and ease of movement, and it remains appealing even today (I wish they'd release more Neoshell products). This model is a stripped-down version of the company's summer standard, the Tsurugi Lite Jacket, designed for running and fastpacking, further reducing weight to the bare minimum. If you're looking for more all-around versatility, the Tsurugi Lite Jacket might be a better choice. In any case, this jacket boasts not only the high breathability of Neoshell, but also excellent ventilation thanks to a diagonal double zipper on the front and slit ventilation under the armpits. Designed for activities that produce more sweat, it promises breathable comfort even in low mountains or midsummer. As always, the color and silhouette are lovely
NORRONA bitihorn dri 1 Jacket
Weight ★☆☆ Waterproof ★★☆ Breathability ★★☆ Comfort ★★☆ Functionality ★★★ Versatility ★★☆
This ultra-lightweight rainwear, made with Norrona's proprietary 2.5-layer dri1 material, has only seen new colors added in 2017, but its performance remains the same. Its unique look and functionality remain unmatched. Ultra-lightweight, extremely comfortable, with plenty of pockets and excellent ventilation, this is a unique piece that takes a unique approach to perfecting all the essential features currently considered in lightweight rainwear
MONTANE MINIMUS JACKET
Weight ★☆☆ Waterproof ★★☆ Breathability ★★☆ Comfort ★★☆ Functionality ★★★ Versatility ★★☆
Montane's standard ultra-light rain shell, which promotes fast and light performance, has been on the market for about two years and has not undergone any major changes this year. However, even if its specs have declined, its overall construction remains outstanding, making it a top pick this year. PERTEX Shield+ is a standard waterproof and breathable material that has been adopted by many manufacturers in recent years, emphasizing lightness. What makes it superior to other models is its meticulous attention to detail, such as the deliberately roughened surface that makes the backpack easier to wear, the excellent three-dimensional cut for comfort, the ample chest pocket, and the hood and mouth guard that are carefully designed to provide reliable protection from rain and wind. While ventilation would be appreciated, it's well worth the trade-off for its light weight
What's the best ultra-lightweight rainwear? What kind of person is it suitable for?
What is ultra-lightweight rainwear?
Of course, there have been many lightweight rainwear models produced up until now. However, at the time, they still had many issues, such as being sticky to the touch and prone to becoming stuffy, and the reality was that even though they were light, they were still difficult to use. However, in recent years, with the spread of high-intensity, short-duration activities such as trail running and fastpacking, many brands and material manufacturers have begun jackets made from lightweight, highly breathable, waterproof and breathable materials that activities. As a result, we now have a wide variety of models to choose from that are not only light, but also vary in comfort and ease of use to suit your purpose and style.
1. It's incredibly light and thin
Traditional rainwear for mountain climbing weighs around 400g to 500g. On the other hand, most rainwear that is positioned as ultra-lightweight weighs just the outer layer in the low 200g range or less . Nowadays, it is not uncommon to find models that weigh less than 100g, which is much lighter than a 350ml can of juice.
2. Flexible, easy to move in, and comfortable to wear
The supple feel is non-stiff. The smooth lining feels instantly recognizable when you put your arms through it. While traditional rainwear had given up on the usual comfort, ultra-lightweight rainwear has made a surprising improvement. Previously, light rainwear inevitably felt slippery against the skin, causing discomfort when sweating. However, with the release of GORE-TEX® C-KNIT™ Backer Technology (hereafter referred to as C-KNIT) in 2015, so-called three-layer constructions, which use a solid lining instead of a laminate, have become mainstream, resulting in a consistently smooth and comfortable feel despite the ultra-lightweight nature of the garment . Other models have also emerged that use stretch fabrics for ease of movement, offering a major advantage: not only are they lightweight, but they also comfortably support active activities that involve a lot of sweating.
3. High breathability keeps you dry even when you sweat
Originally designed for activities such as trail running and cycling (short bursts of movement without carrying large loads of luggage), ultra-lightweight rainwear is made from materials and constructed to have relatively higher breathability than conventional, regular rainwear . This makes ultra-lightweight rainwear comfortable even during intense movement or midsummer activities, making it the perfect outerwear that combines comfort with weather protection.
Incidentally, in terms of breathability, not only are material manufacturers such as eVent, Pertex, Neoshell, and GORE-TEX® developing their own high-performance materials, but outdoor brands are also developing their own high-performance fabrics, resulting in fabric products with an increasingly diverse range of performance and features. Furthermore, the breathability of clothing itself is also affected by the thickness of the fabric and the ventilation structure, so in the future, the key to clothing comfort will likely be not just the quality of the materials, but also the overall construction of the clothing .
4. Waterproof and windproof to withstand sudden rain and wind
Despite being so thin and light, recent models still offer sufficient waterproofing to withstand normal rain and wind. Looking at the "water pressure" used to measure durable waterproofing numerically, for example, Pertex Shield+, a representative lightweight material, has a water pressure of 20,000mm. It's said that 10,000mm is necessary to protect against heavy rain, so it's perfectly usable for day hikes and low-altitude mountain climbing. However, just to be clear, it's not necessarily sufficient for long-term mountaineering, in rainy areas, or in storms on mountains above 2,000m, so don't assume that this is the only gear you can use for all kinds of mountain climbing. It's best to consider it for calm environments like day hikes and trail runs, or for short, intense activities .
5. Incredibly small and highly packable
Example of how the OUTDOOR RESEARCH HELIUM HD Jacket fits. Even clothing with pit zips can fit into this size
Despite all these features, it folds up small enough to fit in the palm of your hand. This compact size is nothing but an advantage for anyone who wants to keep their luggage as minimal as possible
6. Wear it on a sunny day and there's no need to take it off afterwards
It's flexible and easy to move in, and its high waterproof, breathable, and windproof properties mean that it can be used in ways that go beyond just rain gear. In other words, it can be used as a regular outer layer, like a windshell . For example, you can put it on on a chilly morning, and there's no need to take it off when you're climbing a steep forest or on a ridgeline, or when a sudden rain shower hits. This means that even if you're not particularly lazy, you can enjoy the huge time-saving benefits, which is very much appreciated.
7. Perfect for everyday wear and a variety of outdoor activities
Originally, this type of clothing was developed with intense exercise in mind, such as running and biking. Even now, as its range of uses has expanded, it is still ideal for a variety of outdoor activities. Many of the styles and designs are slim, easy to move in, and stylish, and can be worn comfortably both as outerwear for running and as everyday wear, so you can wear it in a variety of ways with just one piece. It's sure to become a staple in your wardrobe.
