Ultralight Adventure Equipment says:
You've asked, and we’ve delivered! The Ultra Circuit SV (Small Volume), is identical to our award winning Ultra Circuit backpack, but with a sleeker smaller volume. This super lightweight and reliable workhorse is backed by a lifetime guarantee. Designed for hikers who crave a sleeker profile without compromising performance, this pack is for those who find their current pack a little too roomy. The Ultra Circuit SV is perfect for 3-5 nights out for those with their gear dialed in. Or, if you need a little extra storage, the removable Top-Y and Bottom strap-system (sold separately) can help customize your on-trail experience.
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.
Hikers everywhere agree; Whether you’re a weekend warrior, L.A.S.H.er, or thru-hiker, the Ultra Circuit SV will keep you moving freely. It's the perfect balance of rugged durability, weight capacity, and weight savings in a comfortable long-hauler. The Ultra Circuit SV is a top choice for hiking any long-distance backpacking trail like the Pacific Crest Trail, Continental Divide Trail, Appalachian Trail and beyond.
Ready to take your adventures to the next level? The Ultra Circuit SV is here to be your trail companion. Explore lighter, hike farther, and embrace the journey!
