Finally bought this after been eyeing for months. This is what they claimed from the official website: 

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. 72-liter volume provides ideal storage for weekend, or extended weekend trips lasting three to four days.

Well, am happy with it, and am bringing my base camp to Annapurna base camp. Yep, initially wanna buy north fake at kathmandu, but then again, this is a good investment i rather buy the durable ones.
