Let me start with the conclusion. The DESCENTE ALLTERRAIN hard shell jacket "CREAS" — the black is just too good.
It comes in five colors: chrome gray, black, navy, gray, and khaki. After agonizing over the choice, I went with black, and so far I don't regret it by even a millimeter.
That said, the price is 60,500 yen (tax included). And honestly, there are aspects where I thought, "yeah, this one isn't for everybody." As someone who actually bought it and wears it, here's my take on both the good points and the things that gave me pause.
What kind of jacket is the CREAS?
"CREAS" is a coined word combining "Creative" and "Assemble." The idea is a hard shell jacket that brings together DESCENTE's technical and development capabilities. Even the name tells you how serious the brand is about it.
Here are the main specs.
- Material: Nylon 100% (outer) / Nylon 100% with polyurethane resin coating (inner), Dermizax fabric
- Waterproofing: 20,000mm water pressure resistance
- Breathability: 10,000g/sqm/24h (B-1 method); also listed as 3,500g/sqm/24h under the A-1 method
- Weight: 480g
- Sizes: SS, S, M, L, O, XO, 2XO
- Country of origin: Vietnam / Price: 60,500 yen (tax included) / Black (BK00) is offered as a Spring-Summer 2026 colorway
A "hard shell" is the general term for outerwear designed to firmly block rain and wind. "Water pressure resistance" indicates how much water pressure the fabric can withstand, while "breathability" indicates how much moisture it can release from the inside — with both, a higher number means better performance. These two properties are inherently at odds with each other, so balancing them is where a hard shell really has to prove itself.
Why the black is just too good
So, why black?
First, the texture. Even within blacks, an overly shiny black can end up looking cheap. The CREAS black isn't the type that throws off excessive gloss — it's a deep, settled, calm black. It never sticks out awkwardly around town.
Second, how easy it is to style. This is where it's genuinely strong. Technical outerwear tends to limit what you can wear underneath, since the colors and paneling assert themselves. But the black CREAS never clashes with whatever you put under it. It works over slacks, over denim, even over a suit setup.
You know that worry about outdoor gear looking out of place in the city? A colorful shell jacket always carries a whiff of the mountains. The black CREAS, by contrast, dissolves into the urban landscape. The performance is fully outdoor-grade, yet visually it holds up as city clothing. That gap is what I love about it.
One caveat that comes with the territory: dust and light-colored marks do show up. If that would bother you, one of the gray options may be less stressful.
Comfort and silhouette — 480g of lightness
The first thing that surprised me when I put it on was the weight. At 480g, it's on the notably light side for a hard shell, and that immediate "wait, this is light" feeling was one of the reasons I decided to buy it.
Then there's the natural stretch of the Dermizax fabric. Plenty of people picture a hard shell as something stiff and crinkly that rustles every time you raise your arms. The CREAS keeps that stiffness well in check, and the noise of the fabric while you move is quiet too. Even moving my arms on a crowded train, I never notice the sound of my own jacket.
It also looks smart when layered. Some outerwear immediately balloons the moment you add something thick underneath, but the CREAS holds its outline. My usual size worked with no issues.
What it feels like in the rain — on the waterproofing
I've worn it in the rain a number of times. My honest impression: even in solid rain, I never felt anything soaking through. Thanks to the durable water repellent finish, water beads up and rolls off the surface, and whatever clings to it comes off with a light shake.
Structurally, the zippers are water-resistant and the seams are sealed with seam tape. Water actually tends to get in not through the fabric itself but through the "gaps" — the zippers and stitching — so having those closed off is reassuring.
Of course, no garment can guarantee you'll stay dry under every possible condition; this is purely my own subjective experience. It's also windproof, and I've genuinely felt the chill on windy days ease up.
The ventilation is almost too practical
This is the single feature that justified the price for me.
The CREAS has a system called dual zip ventilation. Two rows of zippers with mesh fabric in between let outside air in while releasing heat and moisture trapped inside the garment. There's pit zip ventilation under the arms as well.
The biggest enemy of highly waterproof outerwear isn't rain — it's stuffiness. You block the outside, then get soaked by your own sweat from within. On top of the breathability spec, having a physical exit for air makes a real difference. Open them when you're walking and start thinking "this is getting warm," and the feeling lifts right away. Being able to adjust your temperature without taking the jacket off is a huge help on days when you're moving in and out of buildings.
The para hood, plus the cuff and hem adjusters
The hood uses a para hood system. It stows away compactly and can be pulled out quickly when the weather turns, and it's designed to prevent rainwater from pooling in the hood.
This is where it earns its keep as city wear. A hood constantly bunched up at your neck pushes the look toward the outdoors, but stowed away it keeps the collar area clean, and you can deploy it in seconds when the rain arrives. Being able to switch between the two is a big deal.
The cuffs use a block fit adjuster. The fit doesn't degrade when it gets wet, and it's noiseless. Hook-and-loop cuffs make a sound every time you open and close them, so the absence of that is a small but genuinely useful everyday difference. The hem cinches with the Cohaesive™ cord lock system, which noticeably cuts down the cold air coming up from below on windy days.
How to think about 60,500 yen
It's not cheap, plain and simple. That's 60,000 yen for a single jacket.
Still, if you frame that price as the cost of getting both function and design, I'm satisfied with it. Lean toward function and it looks like outdoor gear; lean toward design and it gets weak against wind and rain. Viewed as a piece aiming for the middle ground, the price starts to make sense.
For reference, there are higher-end versions: the GORE-TEX C-KNIT model at 88,000 yen (tax included) and the GORE-TEX PRO model at 121,000 yen (tax included). The women's lineup includes a jacket at 60,500 yen and a coat at 71,500 yen (tax included).
Town use or the outdoors?
My conclusion: an all-rounder that leans toward town use.
Dermizax fabric is built in a direction that suppresses stiffness, minimizes noise while you move, and fits urban life better. Wearing it, I really do feel that this garment's philosophy lives in the city. Commuting, shopping, going out on rainy days, traveling — those everyday scenes are where it shines most.
At the same time, 20,000mm of water pressure resistance is more than enough for everyday rain. For light hiking, camping, or an outdoor event in bad weather, it's a dependable partner. Conversely, if serious mountaineering is your main purpose, looking at the GORE-TEX versions would suit your goals better.
Who it's for, and who it isn't
Recommended for
- People looking for a hard shell that doesn't look out of place in the city
- People who commute or go out often in the rain and want functional outerwear
- People who love black outerwear and value styling versatility
- People who want outerwear that moves easily without bulking up
- People who overheat easily and understand the value of ventilation
Not so recommended for
- People whose main purpose is serious mountaineering or harsh environments (the higher-end GORE-TEX versions are the candidates)
- People who can't accept spending 60,000 yen on a jacket
- People bothered by white dust and marks showing up (consider a color other than black)
- People prioritizing warmth (a hard shell is primarily about waterproofing and wind protection; it isn't a warm garment in itself)
Wrapping up
The black CREAS came remarkably close to answering my wish for "clothing you can wear in the city without giving up performance." 480g of lightness, comfort with no stiffness, peace of mind on rainy days — and above all, that calm, settled black.
It isn't a price point for everyone, and depending on your use case another model may suit you better. Even so, if you're looking for a hard shell to wear around town, I'd love for you to try one on at least once. With the black in particular, I think seeing it in person will tell you everything I'm trying to say.
