Reviews

It's really beautiful, I

"It's really great. I used it for my 29-km 'Trail du Patois' race. It's ultra-lightweight and comfortable. I highly recommend it."

Alexandra S. (5/5)

Hydration pack

"The bag is very lightweight and practical. I tested it during a half marathon. One small downside: the water bottles move around a lot, so I put them in the side pockets. Other than that, it has a really nice design."

Q&A

Hello. Can we put a 2-liter water bladder in the back?
Hello, Thank you for your question. It is certainly possible to place a water bladder in the pocket on the back. However, I should point out that this is not its intended use, and therefore there is no fastening system provided for the tube. Some people sew on a small tab to secure it so it doesn’t move.
