The North Face Base Camp Duffel Bag is the classic bomber expedition duffel. 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. For trips lasting three to four days, grab the medium size for ample room for your gear. Grab the extra-large if you're a goalie on a hockey team and need a place to store your oversized equipment.
