ULA 25th Anniversary Green ULTRA 400X Circuit

ULA ULTRA Circuit – 25th Anniversary Edition

The ULA Circuit you know and love, now reimagined in a special 25th Anniversary Edition that blends proven performance with heritage design and modern materials.
For 25 years, ULA has been part of countless adventures - across deserts, over alpine passes, and along iconic trails like the PCT, AT, and CDT. Since its debut in 2006, the Circuit has become a true trail favorite, earning multiple "Best Gear" awards and remaining one of the most trusted packs among long-distance hikers worldwide.
To celebrate this milestone, ULA has created a limited Anniversary Edition that returns to its roots while embracing cutting-edge innovation. The pack comes in a classic green color, a tribute to ULA’s long-standing connection with green Robic fabrics — now combined with advanced ULTRA 400X, one of the most durable and lightweight materials available today.
The construction is thoughtfully balanced: high-abrasion areas benefit from ultra-durable fabrics, while the overall design remains impressively lightweight (approx. 1091 g). The pack maintains its renowned load-carrying performance thanks to a 1.2 oz carbon fiber and Delrin suspension hoop, a dense internal foam frame, and a single aluminum stay. This combination ensures excellent support, efficient weight transfer, and stability without restricting movement.
Heritage details include a classic open front pocket with static mesh and an elasticized closure, along with original gray grosgrain shockcord tabs. At the same time, modern features such as UltraGrid side pockets, ULTRA hipbelt pockets with YKK AquaGuard zippers, and an integrated 5/8″ top Y-strap closure enhance functionality and durability.
Designed for hikers carrying up to around 16 kg (35 lbs), the Circuit continues to offer the perfect balance of comfort, organization, and reliability, whether you're heading out for a weekend trip or a long-distance thru-hike.
