Review Highlights

Reviews

A must-have

"After using it for several months, it's perfect. It's very lightweight—you can't even feel it. It has plenty of capacity for everyday runs and races up to 20–25 km. It has several pockets for carrying the essentials. I went one size smaller than what was recommended on the website, and it fits perfectly (stick to your usual size)."

Aurelie R. (5/5)

Very satisfied

"I'm very happy with my purchase; it matches the description and my expectations perfectly."

Bastien P. (5/5)

Great!

"Great vest—you don't feel it at all while running. The pockets are well-designed, with just the right amount of storage for my runs (15 km). The adjustable straps are handy, and the floral print is a nice change from the black you see everywhere!"

Anne M. (5/5)

Lightweight and feminine

"Perfect for short trail runs. You have everything you need right at your fingertips."

"He's perfect."

Christelle Q. (5/5)

A very good baby carrier

"A really good baby carrier. It runs large—I ordered a size 2 but ended up going with a size 1. I'm 170 cm tall and weigh 50 kilos."

Elodie L. (5/5)

Practical and lightweight.

"Perfect for outings when you want to keep your hands free."

Jennifer B. (5/5)

Not disappointed

"This backpack is really lightweight and functional, with its various pockets. I used to have a backpack with a hydration bladder in the back, but it really wasn't suitable for running. With the RK3, I can run with complete peace of mind: no discomfort (the water bottles stay securely in place) and no feeling of heaviness on my shoulders. It fits my body perfectly. I approve and highly recommend it 😊👍."

Lydie D. (5/5)

"Lightweight and easy to use—I recommend it"

Anne B. (5/5)

"A very well-designed item—extremely lightweight and practical with the straps. I highly recommend it; plus, the colors and patterns are very subtle."
