It's not your average duffel bag. Made from a durable laminate material, the Base Camp Duffel is a bomber of a bag. Amply resilient to be roughed around in-flight, or to be transported up a mountain via a yak, this is one burly duffel bag. 31-liter volume provides ideal storage for overnighters or day trips. New features include redesigned straps and a small side-zip pocket that fits keys or your passport.
