The Resistor pack was built for epic adventures. At 45 liters, you can fit enough gear for a multi-day trip. The 3D internal wire frame with fully adjustable harness system not only gives you a custom fit, it also optimizes how you carry your load. With a large, top-loading main compartment, it’s easy to fill and unpack. The spindrift collar lets you expand capacity when the need arises – and it always does. You can also stow gear in the expandable stuff pocket. More small details with big impact include a lid security pocket with a key clip, hydration compatibility, extra side pockets with compression straps, a whistle in the sternum strap, and a Recco® transponder for safety outdoors this season.
