Granite Gear Perimeter 50L Backpack – Award-Winning Adjustable Hiking Pack

Custom Fit for Every Body Type
The Perimeter 50L backpack redefines comfort with its innovative adjustable suspension system, designed to accommodate diverse body shapes. Choose between Regular (18-21″) or Long Torso (21-24″) sizes, plus adjustable shoulder width via vertical daisy-chain webbing for a personalized fit. The patent-pending Re-Fit hip belt (26-42″ unisex / 24-40″ women’s) ensures optimal weight distribution, wrapping snugly around your hips for all-day support.

Engineered for Heavy Loads & Comfort
Built with a spring steel perimeter frame and PE board core, this backpack efficiently disperses weight up to 40 lbs (18 kg). The dual-density shoulder harness and load-lifter straps minimize strain, while the removable sternum strap adds stability. Whether trekking rugged trails or multi-day hikes, the Perimeter 50L keeps your gear secure with its cinch-and-roll top closure, compression straps, and stretch-woven pockets for quick access.

Smart Storage & Durability
Stay organized with dual large hip belt pockets (DWR zippers), a removable lid flap, and a bottom compartment for a sleeping pad or rainfly. The Robic high-tenacity nylon fabric (100D/210D) resists abrasion, while the hydration-compatible design includes a sleeve and port.
