RK12 — 12-liter hydration vest for trail running

Great cardigan!

"I tested it on a 40km run. The pack fits well and stays secure; the water bottles don't rattle around. The pockets are pretty handy, though I did have a bit of trouble getting the full 500ml bottles back into the pockets during refueling stops (mine have flat bottoms, which doesn't help). Otherwise, it's a super lightweight pack that you barely notice you're wearing!"

A very nice cardigan

"Since I couldn't see it in the store, I was a bit unsure about this vest, but the fact that it's made in France won me over. I tried it on for the first time and was very impressed by how lightweight, comfortable, and practical it is. I highly recommend it."

Trail Vest

"Very lightweight, fits snugly, and has plenty of pockets. I'd definitely recommend it."

Sandrine P. (4/5)

Almost Perfect

"Very lightweight bag with easy-access storage. The only thing missing is a loop in the back pocket to attach the water bladder."

Q&A

Hello, Could you let me know if there is a pocket for a cell phone on the front? (11-liter trail backpack) Thank you.
Hello, Thank you for your question. There is indeed a pocket designed for a cell phone, but it depends on the size of the phone. Best regards, The Kinetik Team
