Long days between resupplies require a pack designed with ample space and durability. Made with Ultra 100X and EPX 200 material to add a splash of color, the ultralight Arc Haul UltraEPX 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 keep you cool. Featuring adjustable shoulder straps, an interchangeable belt, and a variety of optional modular add-ons, the Arc Haul UltraEPX will allow you to tackle those long days on the trail with a durable ultralight backpack designed to fit you.
