Trail Mountaineer Bag has a clear outdoor inspiration, resulting in a functional and sporty backpack. Characterized by a boxy silhouette and sporty details.

This design leans into the sports-utility mood of the Trail family. It is detailed with webbing-strap-mounted buckles to compress the bag, keeping contents in place. Trail Mountaineer Bag is worn by the padded shoulder straps and secured by a chest strap.

Henry ★★★★★

Got caught in a downpour on a hike last weekend and everything inside stayed bone dry, which is exactly what I bought it for. The boxy shape keeps it from sagging when it's only half full, and the sporty look doesn't hurt either.

Avery U. ★★★★★

The squared-off shape holds way more than it looks like it should, and everything stayed bone dry after a surprise downpour on the trail. The waterproof shell is the real deal, not just a coating that beads up for a week.

Natalie W. ★★★★★

Took this through a rainy weekend hike and everything inside stayed completely dry, which sold me on the waterproofing immediately. The squared shape actually sits nicely against my back and doesn’t flop around when I’m moving fast.
