Review Highlights

Reviews

Highly Rated

"My first real hydration pack. Perfect for trail running and training in the heat of Réunion. Very lightweight and breathable. Washes and dries very easily. Very practical attachment system. Plenty of pockets to hold everything you need. Maybe one or two pockets too many, since it’s easy to mix up the openings. Haven’t tried it with trekking poles yet. I have some minor regrets about the elastic bands that hold the water bottles in place—they’re a bit flimsy. And it’s very difficult to fit 500 ml bottles in them."

The Best of the Best

"Great jacket! It's exceptionally lightweight considering the number of pockets and its carrying capacity, and it's very comfortable. I used to get chafing around my neck with jackets from other brands, but this one works perfectly. No bulging at all, even with two full water bottles."

— Lucas J. (5/5)

Top Product

"A lightweight and super-convenient product for carrying everything, but there's one downside: it's very difficult to fit the 500-ml water bottles—the pockets are too tight, and the elastic straps break easily."
