Patagonia designed this pack to feel incognito on your back and effortlessly carry just what you need for moving quickly and comfortably on hikes, scrambles and cobblestone streets. The U-shaped lid provides easy access to the main compartment, where there’s room for a hydration reservoir, food for a long day of motion and extra clothes in case you meet up with a brewing afternoon thunderstorm. A separate stash pocket holds your smaller, easily misplaced items like sunglasses, topo map and sunscreen. The pack’s exterior has a large stretch pocket in front and quick-stash pockets on the sides for securing extra gear you want to keep handy. We built the women’s-specific 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 waistbelt and shoulder harness have a narrow profile with more taper to fit the female torso and keep your load comfortably centered and close to your back so your gear moves with you, not against you. Compression straps on each side allow you to manage the size of various loads. 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.
