Mountain Hardwear UL 20L Backpack

UL 20L backpack—lightweight, packable, and ready for alpine adventures

What Our Gearhead® Experts Are Saying:

“This is the ultimate pack for lightweight adventures. It’s compact and easy to stash when not in use but durable enough to handle tough trails. The center strap is a genius feature for securing extra gear like a rope or jacket.”

When we’re heading out for a summit push or a lightweight adventure, the Mountain Hardwear UL 20L Backpack is our go-to companion. Built with durable, recycled 200D ripstop nylon, this pack handles rugged conditions while staying ultralight and packable. Its versatile design features a drawstring closure and an innovative center strap for compressing loads or securing bulky gear like climbing ropes.

We love the thoughtful details, like adjustable bottle pockets made for durability, breathable air mesh shoulder straps for comfort, and reflective accents for added visibility. Whether stowing it for backup or carrying it for a quick ascent, this pack proves that big adventures can come in small packages.
