Say hello to the Ultra Circuit, the same Circuit you know and love, only stronger and lighter than ever. Purposefully constructed of Ultra 400 in high abrasion areas (bottom, back panel, and pockets) and Ultra 200 in low abrasion areas (sides, front, and collar), we’ve selected a fabric matrix that maximizes durability while keeping the pack ultralight [33.8 oz!]

In our commitment to making quality, durable backpacks that last a lifetime, we’ve been hesitant to build packs out of many popular ultralight fabrics. Why Ultra? 15x stronger than steel by weight, twice as abrasion resistant as standard 420D nylon, and waterproof to 200 psi, we’ve finally found an ultralight fabric that matches our high standards. Front pocket is ULTRA StretchMesh for added abrasion resistance. Note that to maximize water-resistance of the ULTRA Circuit, these packs do not have bladder hose ports. 

We don’t think there’s a pack out there that compares to the load carrying capabilities, comfort, and durability of the Ultra Circuit. The Ultra Circuit utilizes a 1.2 oz carbon fiber and Delrin suspension hoop, a dense internal foam frame, and a single aluminum stay to give you excellent back panel support, maximum load control, weight transfer, and pack rigidity without limiting your range of movement. Front mesh pocket, dual hipbelt pockets, and Ultra 400 adjustable side pockets make it easy to stay organized whether you’re on a thru or just out for the weekend. If you have your total pack weight down to around 30 pounds and want to feel the freedom of traveling light, the Circuit is for you.
