I’m on the Appalachain Trail right now for the last 30 days and am 100% happy so far. Awesome pack. Probably best on trail.

– John M., ★★★★★

Long days between resupplies requires a pack designed with ample space and durability. Made from Ultra 100X material, the ultralight Arc Haul Ultra backpack is innovatively designed to be a true workhorse from the Sierras to the Shenandoah.

Comfortably transfer your pack’s weight to your hips with our custom Curved Carbon Fiber frame system. The frame also creates a gap between your back and the pack allowing for air flow that helps keeps you cool.

Featuring adjustable shoulder straps, an interchangeable belt, and a variety of optional modular add-ons, the Arc Haul Ultra will allow you to tackle those long days on the trail with a durable ultralight backpack designed to fit you.
