ULA Circuit Ultra 68 L

ULA Ultra Circuit

Multi-award-winning and beloved by long-distance hikers worldwide, the ULA Ultra Circuit has been named Best Gear by Adventure Alan, The Trek, and Treeline Review, and has been the most-used backpack on the Pacific Crest Trail for several years in a row according to the Halfway Anywhere Survey.

The Ultra Circuit is the iconic ULA Circuit in its most advanced version yet - stronger, lighter and more weatherproof than ever. The backpack is built with strategically placed Ultra™ materials where Ultra 400X is used on the most exposed areas such as the bottom, back panel and pockets, while Ultra 200X is used on less exposed panels to keep the weight low. The result is an extremely durable long-distance backpack with an impressively low weight.

Challenge Ultra™ is one of the most advanced materials on the market for ultralight gear - up to 15 times stronger than steel by weight, significantly more abrasion resistant than traditional nylon, and highly water resistant. For extra durability, UltraStretch™ mesh is also used in the front pocket.

What has made Circuit legendary among thru-hikers is the combination of low weight, high comfort and great load transfer. The advanced carrying system with carbon fiber arch, aluminum stay and dense foam frame provides stability and comfort even during longer food carries or heavier packing.

We have chosen to only bring in the Ultra Circuit with ULA's appreciated S-shaped shoulder straps. According to both our own experience and feedback from our customers, they provide a better and more natural fit over the chest and shoulders, which is perceived as more comfortable during long days of packing.

The backpack is designed for long hikes where functionality and reliability are key. The large side pockets and spacious front mesh pocket make it easy to organize and quickly access gear throughout the day. Compression straps and external attachment points also make it easy to customize your pack for different hikes and seasons.

Ultra Circuit is an obvious choice for those who want an ultralight backpack without compromising on comfort, durability or carrying capacity.

How to measure your back length:
