Comfort
The Ultra Circuit 68L delivers exceptional comfort for an ultralight pack, thanks to its thoughtfully engineered suspension and customizable fit. A carbon fiber and Delrin hoop, paired with a central aluminum stay and foam back panel, provides solid load transfer and stability while allowing freedom of movement on the trail. The contoured hipbelt and shoulder straps are densely padded for all-day support, and the Velcro-attached hipbelt system allows you to fine-tune torso length for a personalized fit. With options for J or S curve shoulder straps and multiple sizing configurations, the Ultra Circuit easily manages loads up to 35 pounds, making it a standout choice for long-distance hikers who want ultralight performance without sacrificing comfort.
Weight & Packing
The ULA Equipment Ultra Circuit 68L strikes an ideal balance between weight and functionality, weighing just 36.8 oz with all standard components included. Designed for thru-hikers and minimalist backpackers, it offers a generous 68 liter total capacity, split between a large roll-top main compartment, stretchy front mesh pocket, dual hipbelt pockets, and oversized side water bottle pockets. The pack includes a removable aluminum stay, carbon fiber and Delrin suspension hoop, and a foam back panel, all contributing to excellent support while keeping the weight low. Additional features include built-in compression straps, hydration port access, ice axe/trekking pole loops, and customizable add-ons like a shoulder strap pocket or internal stash pocket. Despite its ultralight build, the Ultra Circuit delivers all the features most long-distance hikers need—without any unnecessary extras.
Price
The Ultra Circuit 68L is priced at $380, reflecting its premium construction, custom fit options, and ultralight performance. While it’s more expensive than entry-level backpacks, the Ultra Circuit is a long-term investment for serious hikers, built with Ultra 400 fabric for outstanding durability and weather resistance, and designed to comfortably handle long-distance miles with minimal weight. The price includes thoughtful features and customization that many ultralight hikers consider well worth the cost.
Quality & Materials
The Ultra Circuit 68L is crafted from Challenge ULTRA fabrics, Ultra 200X and 400X - a material that is waterproof up to 200 psi, over twice as abrasion-resistant as standard 420D nylon, and boasts a strength-to-weight ratio 15 times stronger than steel by weight. These ULTRA fabrics are made from 100% recycled polyester, delivering enhanced UV resistance, water shedding, and longevity compared to traditional Robic or Dyneema-based packs. The UltraStretch™ mesh front pocket is engineered for durability and minimal sag over time, while the overall build quality, including taped seams, robust webbing, premium buckles, and precision construction in the USA, reflects ULA’s reputation for long-term reliability and trail-ready toughness

Who is this For?
The ULA Equipment Ultra Circuit 68L is ideal for thru-hikers and long-distance backpackers with total loads up to 35 pounds, offering full-frame support without the bulk. It’s a great fit for those who want a customizable unisex pack, with options for J or S curve shoulder straps, four torso lengths, and multiple hipbelt sizes to dial in comfort. Built with highly durable, water-resistant Ultra fabric, it’s perfect for hikers who value reliability without needing cutting-edge tech features. The pack also appeals to those who appreciate made-in-USA craftsmanship and the added assurance of a lifetime warranty. However, it’s less suited for ultralight purists seeking frameless sub-2 lb packs, or for winter mountaineers needing full waterproof protection and larger load-hauling capability.
