Ultralight Adventure Equipment says:
You've asked, and we’ve delivered! The Circuit SV (Small Volume), is identical to our award winning 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 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.
Hikers everywhere agree; Whether you’re a weekend warrior, L.A.S.H.er, or thru-hiker, the 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 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 Circuit SV is here to be your trail companion. Explore lighter, hike farther, and embrace the journey!
Our Verdict
I’ve been impressed by how ULA has refined this pack without losing what made the original Circuit such a favourite. The SV 48 is a tighter, sleeker version, designed for those who have streamlined their gear and want a pack that reflects their efficiency. At just 1064g (Medium torso & medium hipbelt), it’s not only light but also feels properly tough, thanks to the 400 Robic.
The frame and suspension hold loads up to 16kg well, and the fit adjustments make it easy to dial in. The stretch mesh pocket, made from UltraStretch, is tougher than most and easily accommodates wet kit or snacks without fuss. The hipbelt pockets are larger, keeping gear you need close at hand.
