Fully adjustable, fully comfortable.

Pack a weekend's worth of camping supplies in Granite Gear's Lutsen 45 Backpack and hike into the woods comfortably. Its Re-Fit Air Current suspension system uses dual-density padding with ventilated slits for circulated airflow, and Re-Fit adjusts the shoulder straps and hip belt both vertically and horizontally for a customized fit. Granite Gear made this pack out of durable-yet-light ripstop with a DWR treatment for reliable resistance against rain.
The Lutsen is a traditional top loader with a detachable top lid that doubles as a day pack for short hikes away from the campsite. There's a hydration sleeve inside the backpack with a port for your reservoir's tube. The bottom gear loops adjust to secure trekking poles. Granite Gear added two stretchy side pockets for water bottles, a stretchy front pocket for layers, and two zippered hip belt pockets, one of which has extreme water-resistance to protect electronics.
