Fantastic move to the Arc Haul pack from a traditional internal frame type pack. Although I didn't really need a 70L pack, I decided to go with the biggest I could get as the top rolls down if compartment is not filled up.

The Arc Haul Ultra is your trail-tested partner for epic thru-hikes and everyday escapes. Crafted from ultra-durable Ultra 100X fabric, this powerhouse of a pack balances comfort and strength with barely-there weight.

Designed with women in mind, it helps you carry with confidence. Our signature curved carbon fiber Arc Frame transfers weight to your hips and creates a breathable space between your back and the pack. No more sweaty discomfort during long climbs or hot days.

With a patented adjustable torso height, interchangeable shoulder straps, and a padded belt that hugs your shape, the Arc Haul Ultra isn’t just made to fit, it’s made to fit you. Add modular accessories to suit your adventure style and you’re ready to take on big miles with comfort, grace, and grit.

The Arc Pro is what happens when a proven long-distance backpack gets stripped down and rebuilt around durability, simplicity, and effortless access. Delivering a technical look and serious trail performance, the Arc Pro is built with rugged Ultra 100X and Ultra TenX fabric for the demands of long-distance hiking.

Venom Stretch Mesh center, side, and bottom pockets keep frequently used gear easily accessible, and a zippered 3D mesh sleeve gives you a convenient spot to quickly stow the included foam sit pad.

Underneath the streamlined exterior is our proven curved carbon fiber Arc Frame and adjustable torso height system, designed to keep weight off your back while delivering the ventilation, adjustability, and carrying comfort long-distance hikers depend on. With interchangeable shoulder straps and belts, plus tons of modular add-ons, the Arc Pro is tough where it needs to be, simple where it should be, and cleaner-looking from every angle. It’s the pack you’ll wonder how you lived without.

Also available in 50L and 60L versions.
