Ultra-lightweight rainwear 2018 that you can't miss this season

It weighs less than 100g? So, how comfortable is it to wear? The world of incredibly light and compact ultra-light rainwear, which we have been actively featuring on this site for the past two years, is no longer the same as it was just a few years ago when anything under 300g was considered good. Now, even something under 100g elicits the above reaction, and this year has seen it evolve at an incredible rate

Continuing from last year, there has been an increase in products that are not only lightweight but also breathable, comfortable, and easy to move in, making them suitable for a variety of activities. Above all, the number of brands and items entering the market this year is even greater than last year. From serious mountaineering brands to running brands, the sheer number of new products from a multitude of brands are appearing like stars, competing for popularity, which could be said to be the biggest feature of this year

This year, we've been checking out ultra-lightweight rainwear, a symbol of the dog-year evolution of outdoor gear, and as is becoming an annual tradition, we've compiled a list of noteworthy models, so let's get started right away

As always, the most important criterion for selecting something is whether or not I wanted it (or whether or not I couldn't help but buy it)

However, this time, because the previous standard of "approximately 300g or less" would have broadened the scope of eligible models too much, we have lowered the ultra-lightweight standard to around 200g. In fact, in recent years, rainwear for general mountain climbing has achieved considerable performance even at around 300g. As a result, we plan to introduce some of the models that we selected as ultra-lightweight rainwear until last year in a special feature on rainwear for serious mountain climbing, which will be announced at a later date

Berghaus Hyper 100 Jacket

Weight ★★★ Waterproof ★★☆ Breathability ★★☆ Comfort ★★★ Functionality ★☆☆ Versatility ★★☆

The biggest attraction this season is undoubtedly the "world's lightest 3-layer" waterproof and breathable jacket (according to the brand), which won undisputed gold awards at both the 2016 OutDoor Show and ISPO 2017. This supreme item is the result of generous use of innovative technology by the MtnHaus design team, the cutting-edge product development team of this leading British outdoor brand

Of course, our editorial team got hold of it as soon as it was released. The moment we put it on, we were immediately captivated by its lightness (97g for a size M) and its supple feel, just as we'd hoped. The previous model (the Vaporlite Hypershell Jacket) was lighter at 85g, but because it was a 2.5-layer jacket, it had to settle for a lining that felt like vinyl, so this is a major improvement. The company's innovative proprietary Hydroshell Elite Pro material is the company's lightest and most breathable waterproof membrane yet, and although the specifications haven't been released, we can expect it to offer even better waterproofing and comfort than the previous model.

It's not just the lightness that's astounding. The unique three-dimensional cut allows for a natural fit around the shoulders and a minimalist design, while the hybrid hood and cuffs with elastic and flaps keep out the rain as much as possible despite the lightweight design. The addition of an inner pocket (none of the previous model) makes this model one of the lightest in the world, yet also boasts functionality that makes it the top recommendation of the year for those who enjoy short, high-intensity activities like trail runs and short speed hikes

THE NORTH FACE Strike Trail Hoodie (or Strike Jacket)

Weight ★★★ Waterproof ★★☆ Breathability ★★★ Comfort ★★☆ Functionality ★☆☆ Versatility ★☆☆

The North Face, which has been rapidly releasing lineups focused on fastpacking and trail running since last season, has released its latest offering: an ultra-thin, ultra-lightweight waterproof shell designed for race use. Continuing from last year, the company's proprietary HYVENT Flyweight (3-layer) material boasts reliable specs of 20,000mm water resistance and 40,000g breathability. Furthermore, this model eliminates pockets and minimizes the Velcro cuffs and drawcords for adjusting the hem and hood, resulting in the company's lightest jacket ever at just 110g. Of course, the 3-layer lining remains as comfortable and smooth as ever. Its thoroughly run-specific features, such as a clear color that lets you see your race number, are sure to be a great attraction for race-minded individuals

The Strike Jacket, which we introduced last year, is still on sale. This is also a highly recommended ultra-lightweight model that is well-balanced and easy to use not only for running but also for hiking and everyday wear.

Salomon Bonatti Pro WP Jacket

Weight ★★☆ Waterproof ★★☆ Breathability ★★☆ Comfort ★★☆ Functionality ★★★ Versatility ★☆☆

The Bonatti Pro WP Jacket's impressive details make it a worthy tribute to a top mountain racing brand. First of all, the supple outer fabric is not overly rough, a welcome addition for running. The back gusset, thanks to MotionFit construction, allows for unrestricted freedom of movement, allowing for exceptional ease of movement despite the slim silhouette. It's packed with features perfectly tailored to running, including a hood with elastic that fits snugly around the forehead to prevent water from entering, reflectors for safety even at night, a packable design that allows for storage without a stuff sack, and chest buttons that prevent flapping even when the waterproof zipper is open

Marmot ZERO Penetrate Jacket

Weight ★★★ Waterproof ★★☆ Breathability ★★★ Comfort ★★☆ Functionality ★★☆ Versatility ★★☆

Marmot, which has recently been known for its unique UL-style items, including collaborations with Hiker's Depot's Tsuchiya, an important figure in ultralight hiking in Japan, has now released a new, ultra-lightweight rainwear that is a major upgrade to the previous model, the ZERO STORM, which was already extremely light

The unique MemBrain Strata is 2.5 layers, yet surprisingly, it doesn't feel sticky at all. Its water resistance of 20,000mm and breathability of 20,000g are also satisfactory. And best of all, the weight has dropped even further from the previous model to 138g, making it one of the lightest jackets in the world. Personally, the most impressive feature is the hand pockets that double as ventilation. The clever design ensures breathability while functioning as a pocket, and I couldn't help but say, "I see." I'm also impressed by the well-thought-out design of the hood, which fits perfectly even without any adjustment

This model has been completely transformed from the somewhat ordinary design of the previous model into a unique model with features that are unique to this model, and it should be able to perform well not only for trail running, but also for general outdoor activities that prioritize lightness, such as fastpacking

Patagonia Storm Racer Jacket

Weight ★★☆ Waterproof ★★☆ Breathability ★★☆ Comfort ★★☆ Functionality ★★☆ Versatility ★★☆

Patagonia's mountain racing rain jacket has finally been updated this year. The previous model was a slightly underwhelming 2.5-layer jacket weighing just 270g, but this new model features a comfortable 3-layer fabric and weighs just 170g, making it a cutting-edge model

As always, the company's slim, stress-free three-dimensional cut is impressive, and the subtle stretch improves ease of movement. The cuffs are partially elastic, achieving both lightness and a good fit. The hood can be adjusted with a cord lock, and the chest pocket is packable and can be turned inside out for storage, demonstrating the company's unique pursuit of not only lightness but also overall usability

MONTANE MINIMUS 777 JACKET

Weight ★★★ Waterproof ★★☆ Breathability ★★☆ Comfort ★★★ Functionality ★★☆ Versatility ★★☆

Montane's lightest waterproof shell, which took first place in a comparison test conducted by our editorial team last year, remains unchanged from last year. Despite this, it still stands out in terms of performance. This year, the 3-layer jacket, which uses the lightweight waterproof and breathable membrane "Pertex Shield +," which has been supplied to many brands around the world, offers a supple and comfortable feel and stays dry even when sweating, ensuring uncompromising comfort. The three-dimensional cut of the arms, which ensures high mobility when running and climbing, remains as excellent as ever. When it comes to fastpacking, trail running, or emergency gear, where lightweight is essential, there's no better ally

OMM Aether Jacket

Weight ★☆☆ Waterproof ★☆☆ Breathability ★★★ Comfort ★★☆ Functionality ★★★ Versatility ★★★

This 2016 OutDoor Show award-winning mountain running jacket was redesigned in the fall of 2016. While its weight of approximately 200g may not be exceptionally light, its high level of weather resistance, durability, and functionality make up for this jacket's greatest innovation. eVent has a long history as a waterproof and breathable membrane rivaling GORE-TEX, boasting breathability that feels like the garment is breathing. The suppleness of the finely woven fabric, the comfortable 3-layer fit, and the streamlined silhouette created by the carefully designed draping will undoubtedly boost your motivation for the race. Its unique design, including a comfortable hood, adjustable cuffs that can be closed or have thumbholes, and a hem and waist that are designed to prevent roll-up, make it easy to see why so many people want to own this jacket despite its high price

Mont-Bell Versalite Jacket

Weight ★★☆ Waterproof ★★☆ Breathability ★☆☆ Comfort ★☆☆ Functionality ★☆☆ Versatility ★★★

Although it's been around for a while, its 168g weight is still competitively light. To be honest, in 2017, I wish it had a bit more performance, such as breathability, a more comfortable lining, hand pockets on both sides, and Velcro adjustments on the cuffs. But above all, its excellent value for money is particularly noteworthy. This is definitely an easy choice for those who prefer light and fast activities like trail running and fastpacking and don't want to make any major mistakes. It's also a slightly looser fit than Western models, so it's recommended for those who like that fit

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. Breathable 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 so good about ultra-lightweight rainwear? Who 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

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.
