25th Anniversary Green ULTRA 400X Circuit

For 25 years, we’ve been blessed to adventure with you.

Across deserts and over alpine passes. From the first time your feet touched a trail to the confident (yet weary) final steps of a thru. From the PCT, AT, and CDT, to all the unnamed trails in between, we’ve been there, cheering you on.

What began as one man, a sewing machine, and an idea has grown into a global community of hikers who trust us with their biggest dreams.

Since its debut in 2006, the Circuit has been a trail favorite. Year after year, it’s earned Best Gear awards. For more than a decade, it’s remained one of the most popular packs on the Pacific Crest. It’s the one hikers return to, again and again.

To celebrate 25 years on the trail, we’ve built something to commemorate our history and the friendships we’ve built along the way.

This limited 25th Anniversary Edition Circuit returns to our roots in Green (a nod to ULAs long-standing love affair with green Robic!) while embracing modernity with ULTRA 400X, one of the most advanced ultralight backpacking materials.

Heritage details include a classic open static mesh front pleated pocket with elasticized top closure and original gray grosgrain shockcord tabs. Of course, it had to be green!

The 25th Anniversary Edition also includes UltraGrid side pockets, a built in 5/8″ top Y-strap closure, and ULTRA hipbelt pockets with YKK AquaGuard zippers.

In true ULA fashion, we’ve built it with only the best materials and construction.
