Muir III Special Edition Backpack

The Muir III Special Edition is the latest evolution of the Muir Project, designed in collaboration with Carryology.

Crafted from translucent XPAC UX10. This ultralight and ultra-strong fabric allows the bright orange liner to glow through from within, creating a unique look & feel that’s not for the faint-hearted.

Built for one-and-a-half bag travel, the Muir III has a huge U-Zip opening, multiple access options and whole host of easily accessible pockets to help you stay organised on the go.

The removable sling provides additional internal storage, or can be removed for lightweight adventures.
