We made our smallest Nine Trails Pack with a design that sticks to your back and moves with you, not against you, on long backcountry rides, fast-paced trail runs and ridge scrambles. The full-access, panel-loading design provides instant entry to the pack’s interior where there’s room for the 2-liter HydraPak® reservoir (included), spare tubes, food for a full day of riding and extra clothes for the descent. A separate front pocket opens with a clamshell zipper and holds smaller, easily misplaced items like a tool kit, sunglasses and some spare cash for grabbing a coffee at the end of the day. The pack’s exterior has a large stretch pocket on the front and quick-stash pockets on the sides for securing extra gear you want to keep within reach; hip-belt pockets keep your must-haves close at hand. We built the back panel from mono-mesh to prevent moisture buildup and provide excellent airflow; it’s the most breathable back panel we’ve ever made. Designed with perforated foam, the padded shoulder harness and waistbelt keep your load comfortably centered and pasted to your back even on the worst white-knuckle descents. Made of lightweight yet highly durable 4.2-oz 210-denier CORDURA® 100% nylon ripstop with a 3.3-oz 200-denier 100% polyester lining. Both fabrics are treated with a polyurethane coating and a DWR (durable water repellent) finish.
