Reviews

A lightweight and comfortable product

"Great product—lightweight and functional. The only downside is the three-point closures if you have a bit of a belly 🤣🤣"

— Regis D. (4/5)

Lightweight and convenient

"Comfortable to wear and easy to use. It has plenty of deep pockets. Although lightweight, it can hold a lot of items. The water bottles are perfectly positioned thanks to the small black elastic band, which lets you drink without wasting too much time."

— Lise F. (5/5)

Kinetik Vest

"Beautiful and as practical as ever"

Tested over a 75-kilometer distance

"Tested over a 75-km ride this weekend in brutal conditions—lightweight and high-quality"

This running vest

"This running vest is a great product for trail running! It’s very lightweight and unobtrusive—you don’t feel it at all while running. The two water bottles included are practical and well-designed, but be sure to wash them thoroughly before your first use to avoid any plastic taste. Plus, the colorful design adds an extra touch of fun to your run. I highly recommend it!"

— Harmonie D. (5/5)

Very happy: great

"Very happy: they look great and seem very comfortable. However, I bought two (the leopard-print version for my wife), and we only received two water bottles (instead of four, I assume)."

— Laurent L. (5/5)
