Awesome Jacket

"Perfect after a 2-hour test run in the rain. Can't wait to try it out at the Saint-Élyon this winter."

Mathieu M. (5/5)

Good value for the money

"No complaints, no flaws."

Etienne J. (4/5)

Waterproof Jacket

"I'm very happy with this jacket after three trail runs in the rain. The fit is perfect—the recommended size matches my body type exactly—and it's so lightweight that I forget I'm even wearing it during my runs. I have no complaints about its waterproofing. I highly recommend it!"

Julien R. (5/5)

Perfect

"Tested on a 65 km ride in Brittany. Absolutely perfect. I recommend it."

Alexandre T. (5/5)

All good

"It matches the description and fits well. I haven't had a chance to test it in tough conditions yet, but the good design and apparent quality suggest it'll do the trick!"

Alain A. (5/5)

Gorgeous jacket

"The jacket is technically perfect, with pockets that let you stay hydrated and a handy storage pocket on the back 👌 The only downside is that it runs large, even with the bag. If I'd known, I would have tried the jacket and bag set."

Thibaut V. (4/5)

A gorgeous jacket—super breathable and waterproof

"A really well-designed trail running jacket with waterproofing that lives up to its promises. I've already tested it on long runs in the rain, and it performs just as it should."

Top-notch

"I recommend this K-Way—it's perfect for any outing and works great in Brittany 😉"

Jonathan D. (5/5)

The two chest pockets provide access to the bag—is that right? You can't tell from the photos.
