Rainwear today, with increasing performance accelerating, has waterproof and breathable properties that are hard to imagine from a few years ago, making it less likely to get stuffy and more comfortable. Very lightweight models are also appearing one after another. That's not to say that only authentic outdoor brands can make such high-performance rainwear. Highly breathable and non-smooth rainwear. Workman has also released rainwear that is attractive because it doesn't get stuffy, but is lightweight and compact.
When you think of Workman, you'll be surprised at how cost and performance are, but the items we're introducing today are also unbeatable.

Impressions used
The test fields are from March to April and May, including Tanzawa, Okutama, and Izu. We will review what I felt after wearing it in the rain despite the unusual snowfall for March.
A simple design allows you to seamlessly navigate between the mountains and the city
A highlight on the inconspicuous cuffs
I the Inarem Premium Air Rain Jacket, the first thing I liked was the simple design with a clean silhouette. It's not "Yamayama" in a good way, and it's easy for anyone to match. Many clothing has a brand logo placed so that you can easily see the brand, but this one has a logo on the cuffs. The logo also has a calm design and is actually nice, and at first glance it doesn't seem like Workman, and it is comparable to the shells of other outdoor brands.
The plain design makes the solid, calm color scheme not too sporty and doesn't look sloppy, and comes in six colors: black, blue, yellow, red, beige, and sage green, and the calm colors make it a great everyday wear.
Highly stretchable and does not interfere with movement
Another thing that encourages people to actively wear it in the mountains and in the city is their high elasticity. Because it is stretchy, it is less likely to hinder movement, and the elbows that are bent and stretched are made of three-dimensional stitching, making it easy to move around, as well as running, and not just mountain climbing, but also stressful even in activities with a lot of movement, such as running.
The humidity permeability is a threat to 40,000g/m²/24h High moisture permeability that won't get stuffy even when worn.
It's not only simple design and stretchy. Inarem Premium Air Rain Jacket is its high moisture permeability. The breathability of this jacket is surprisingly "40,000g/m2/24h", which is comparable to a full-fledged outdoor brand. It's amazing that clothing with such specs is available at a low price that brings you change for 4,000 yen. Usually, the specs are worth tens of thousands of yen if it is a genuine outdoor brand clothing.
In field tests, I spent about five hours wearing it to see how true his abilities are. I actually thought it would rain, and tried wearing rain pants to make it look as realistic as possible, and when I tried it out, I definitely couldn't feel any discomfort from stuffiness. Strictly speaking, I was able to act while being suppressed by the feeling of stuffiness before I felt uncomfortable.
One of the concerns about rainwear is that sweating while you are on the move can make your clothes get stuffy, and sweating can make your clothes get wet, leading to coldness and unpleasant feelings, but I have the Inarem Premium Air Rain Jacket does not get wet due to the sweat coming back.
Water resistance and water repellent that can be adequately suited by choosing the field
The Inarem Premium Air Rain Jacket a high moisture permeability , but when you try to pour water drops on the water-repellent fabric, you can see how water-repellent it is. However, when I tried it as rainwear, it felt a little unreliable. The rain jacket has a waterproof resistant 10,000mm water pressure, but in actual tests, if the rain lasted a long period of heavy rain, I was concerned about the wetness on the inside. In that sense, it is not recommended at all for those looking for rainwear like armor that will keep you comfortable no matter how bad the weather is.
However, this does not mean that it cannot be used as rainwear, but it is very satisfying to prepare for the rain on a short day trip or to walk around a forest covered in trees.
Although it is difficult to choose tools that are designed to be in a harsh environment, this does not necessarily mean that you need to choose such high-spec tools. I feel that there are many opportunities for light hiking, low mountain climbing, long trail section hiking, and entry models for beginners before they start serious mountain climbing. Also, hikers with a certain level of experience will be able to use them based on their own experience and skills.
High functionality with careful attention to detail
Although the water-resistant surface makes it unreliable as rainwear, the Inarem Premium Air Rain Jacket . It also has a hood adjuster and the eaves are designed to be longer, so it can handle rain from the front.
The zipper has a waterproof zipper that makes it difficult for water to enter, and the inside flap allows water to flow without wetting the clothing inside. However, it is not completely waterproof and does not have a double flap structure, so be careful as it will get flooded if there is heavy rain that is lying down.
In addition, the cuffs are shirred and Velcro, allowing for adjustable fit. You can adjust the fit by using the drawcord at the hem. The Inarem Premium Air Rain Jacket has features that are comparable to general rainwear from a functional standpoint , but what caught my eye was the durability. The drawcords used on the hood and hem are made of extremely thin bungee cords, which can make you feel uneasy, and when you squeeze the hood adjuster, the excess drawcords hit your face and get in the way. Considering the price, I don't know if it's okay to ask for more, but you have to be prepared that the construction itself is far from a sense of security that can be used for a long time.
Lightweight and compact, highly portable
As for weight, performance changes dramatically depending on the durability, functionality, and the number of layers of the product, so I understand that it is too early to simply the Inarem Premium Air Rain Jacket is lightweight, and if you look at it under the conditions of "rainwear that can be used in low mountains," I think it can be said that the actual measured weight of the 3L size I chose is 215g, which is lightweight.
Some of the rainwear available today are the lightest class, and some models are below 150g, while others have a solid durability and high security model that is around 300g. At around 200g, it could be said to be a lightweight model.
Furthermore, it is packable, so if you turn the entire piece over and roll it up into the chest pocket, you can pack the main unit without needing a storage bag. Once stored, it is compact enough to fit in your palm, and once it's this small, no matter how small you put it in your backpack, it won't put any strain on the space. It can be put in a pocket so the storage bag won't be lost, so it's a great feature for me, who is lazy and has a packable design.
Summary: Lightweight, highly breathable rainwear can be purchased at such an affordable price!
It's only surprising that rainwear, which was once known as a premium model, is available for such a price, with lightness and excellent breathability. Of course, it is not of the same quality as such a premium model, but even after taking that into account, its ease of movement, design, and cost-effectiveness are still attractive. Not only is the clothing lighter, but it can also be used as a clothing item, so it can be used both as a clothing item, which will help reduce the weight of your equipment.
The results were somewhat uncertain about waterproof surfaces, but if you were to climb a day trip from half a day in the summer when the weather was stable, I felt that it would be practical enough to carry it on or to use as an outerwear that would protect you from the wind. The author is as light as possible and is UL oriented. For mountain hiking and hiking that doesn't exceed the limits of the forest, I'd like to sneak an Inarem Premium Air Rain Jacket

From spring to autumn, I chase after char deep in the mountains and go fishing in the mountain stream. We walked the mountains in search of spectacular views that cannot be seen from the ground. Camping to be healed by the bonfire. Snowboarding is a floating mountain with a mountain of silver.
