Used this for a 14-mile day hike with about 15 pounds of water and layers and honestly forgot I was wearing it. The vest-style straps distribute weight across your shoulders and chest instead of hanging off your back. Stretchy side pockets fit tall water bottles perfectly. This is my new favorite piece of gear.
I'm a trail runner who does long days and this bag is exactly the middle ground between a running vest and a full daypack. Recycled nylon feels durable without the weight penalty. The organization is minimal, which I like, though if you carry lots of small items you might miss pockets. Great price for what it is.
Light, comfy, perfect size.
Bought this for hiking but it's become my personal item for flights. It cinches down small when empty and holds a surprising amount. The vest straps look a little different in the airport but they're comfortable enough to wear all day through layovers. Straps took a couple trips to dial in the adjustment.
I'm 71 and walk 8-10 miles a few times a week, and traditional backpack straps always dug into my shoulders. The vest design spreads the load so evenly that my old shoulder ache is gone. Holds my water, snacks, layers, and a book for the bench break. Quality feels excellent.
The 28L is more like 24L in practice once you account for the tapered shape. Great for minimalist day hikes, tight for winter loads with extra layers. Build quality and comfort are genuinely excellent though — just size your expectations.
The nylon feels thin but has shrugged off brush and granite scrambles without a mark. Zippers are smooth and the sternum adjusters stay put. No hip belt, which is fine for the weight I carry. Solid 4 stars.
Six months in with weekly use and zero issues. The straps mold to your body in a way regular packs don't, and bouncing while running is basically eliminated. Colorway gets compliments too.
Fit and weight are top-notch, no argument there. But if you're the type who likes a lid pocket, key clips, and dividers, this isn't it — it's basically one big space plus side pockets. Depends on your style.
The vest straps on mine kept loosening over the course of a hike no matter how hard I cinched them. Comfort when properly adjusted was good, but constantly re-tightening ruined the experience. Returning it.
