Review Highlights

Reviews

A very good product, but. . .

"A very good vest—it runs slightly small but fits well thanks to the adjustment dial. I used it on a 60k trail run with the 2L Hydrocore bladder and two 500ml bladders on the front. The only downside is that the 500-ml bottles, with their rigid bases, cause pain in my ribs despite the anti-chafing reinforcements on the vest. I’m not sure if this is because the vest is too tight or not tight enough. Otherwise, it’s a great product."

Jérôme C. (4/5)

As described

"I'm a big guy with a chest circumference of 120 cm, and I had a really hard time finding a comfortable vest that fit perfectly—and this vest completely met my expectations. I recommend this product."

Frederic F. (4/5)

Perfect!

"Perfect for trail runs—you don't even feel it, or the items in the back pocket. It stays in place while running, which is really nice. I have a size 2, and I definitely wouldn't want anything smaller."

Rose-Erine E. (5/5)

RK15

"Size 2. A little tight when the side panels are full."

Nicolas N. (5/5)

Very good equipment

"Overall, it's great gear, but it squeezes my chest a little too much."

Johann S. (4/5)

Light, pleasant—what can I say about

"Lightweight, comfortable—what more can I say? Excellent gear."

Nicolas S. (5/5)

R15 Evaluation Pack

"A great hydration vest that doesn't bounce around. hydrolock think the hydrolock pack is essential for getting the most out of the vest. After my training sessions, I'll still have the real-world test to go through starting in late March."

Dominique S. (5/5)

Functional Bag

"It's practical with all its pockets, but be careful—it runs very small. For runners with a V-shaped, very muscular build, don't rely solely on the chest measurement. So, while waiting for the size 3 or 4 bag—which is currently unavailable—instead of size 2, which had been recommended based on the chest measurement."

ISABELLE T. (3/5)

Stunning

"The bag is great, thanks"

Owenn R. (5/5)

Far too fragile

"Too flimsy! The seams are coming apart, and the fasteners on the front are coming loose. It's causing irritation at the back of my neck."
