Review Highlights

Reviews

Very satisfied

"The design is great, and the vest is super light. It stays in place well when I run. As for the water bottles, they slide down a bit into the bottom of the pocket as I empty them, but it's not too bothersome."

— Ella (5/5)

Extra Lightweight

"This is a very high-quality vest; I recommend your brand to everyone."

— Sophie D. (5/5)

I wouldn't have bought another one.

"I bought my first 3L Rocket at the beginning of 2020. I use it for every training session and on short trail runs—it’s an absolute must-have for me. You barely notice it’s there, and it lets you carry just the essentials. On the 2020 model, the 400 ml water bottles and drinking straws held up well, too. But the little scrunchie to tear (front pockets), and the drinking straws are leaking. So, I just received the new model, which features significantly improved front pockets and the rounded shape of the 500 ml water bottles. In short, a no-brainer purchase (and I’m actually very surprised the price hasn’t changed in five and a half years—kudos to Kinetik). For maintenance, I regularly wash it in the machine on a 30-minute cold cycle, in a laundry net. Great product. Can’t wait to try out the new one.”
