ULA Equipment's Circuit SV Backpack is a lightweight and reliable workhorse pack with a 48L capacity. This framed pack offers the perfect balance of durability, comfort, and ultralight design for long-distance hikers and backpackers. Built with a sturdy UL frame, this pack provides excellent load transfer to the hips, reducing strain on the shoulders for a more efficient carry.

Designed for hikers who crave a sleeker profile that doesn't compromise on performance, this pack is built to go the distance. There’s a reason ULA packs are a top choice for thru-hikers and adventurers!

- Removable hip belt
- Hip belt with larger-than-average pockets and 4-point adjustable for best fit
- Roll-top closure with Y-strap for top compression
- Ice axe and trekking pole loops
- Adjustable torso height by moving the hip belt up or down along the back of the pack
- Load-lifters for an easier carry
- Load adjuster straps at the bottom of the pack let you pull your pack closer to your body for a more comfortable distribution of weightÂ
- Padded back panelÂ
- Contoured "S" shoulder straps that better hug your shoulder slope
- Large front mesh pocket
