"I recommend them. They fit well, protect against the elements, and really kept me warm after the GRP."
— Sven B. (5/5)
"After a lot of research to find a rain jacket suitable for trail running, this is the best jacket I've found—and it's very reasonably priced for the quality! I tested it in the rain and in strong winds, and it held up really well; the breathability is top-notch—it doesn't feel like a sauna at all. The various design features—like being able to pack it into its own pocket, fastening it at the front with just a snap, or unzipping it from the bottom to access the bottom pocket of the hydration vest—are really great. The fit is perfect for wearing a hydration vest under the jacket and easily putting on or taking off the jacket if conditions change."

"I bought this jacket to run a 25K night trail run in the middle of March. It rained all evening, but I didn't feel the cold or the dampness at all with this jacket. It's really great."
— Ariane X. (5/5)
"I'm very happy with the jacket. It's very comfortable, warm, and waterproof. It runs a bit large, though, and it could use an inside pocket for a cell phone."
— Stéphane D. (4/5)
"As soon as I bought it, I was able to test it in harsh conditions—in cold, windy weather below -3°C, then in light rain, and finally in the snow under my ski jacket—and I can confirm that it’s completely waterproof; the quality is top-notch. The reasons for deducting one star are as follows: - It’s difficult to roll it up into a bag, so it’s hard to do so while running; - I think it’s a shame there isn’t a small exterior or interior pocket; - There’s no reflective strip—it’s a shame the white lettering isn’t reflective either. . ."
— Bruno C. (4/5)
"I'm thrilled with this jacket. I've tested it in the damp weather of the North. It's very lightweight and comfortable to wear. It's excellent quality, and I love the color. My wife has the same one. The women's version is slightly different in color, so there's no risk of mixing them up! We highly recommend it!"
— David C. (5/5)
"A great jacket—I tested it in the rain, wind, and sub-zero temperatures. It has a roomy fit and runs a bit large, so I’d recommend sizing down for a more form-fitting look... Very satisfied with the quality and the fast delivery, but it’s a shame I had to pay for the return due to a sizing mistake..."
— REMY H. (5/5)
"Very good quality, and lightweight; runs a little large"
— Julien (5/5)

— Christophe C. (5/5)
"Runs large, great value for the price"
— JULIEN M. (5/5)
