Good value for 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 fits my body type perfectly—it's so lightweight that I forget I'm even wearing it during my runs, and 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 highly 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 solid design and apparent quality suggest it'll hold up!"

Alain A. (5/5)

Gorgeous jacket

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

Thibaut V. (4/5)

A beautiful jacket—super breathable and waterproof

"A superbly 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."
