The wheeled duffle bag boasts an impressive 120 litre capacity for holding and transporting your belongings. When not in use, many backpack straps simply detach for storage in the main compartment (this keeps them out of airport conveyor belts). Throw in storm flaps over the top zipper, an expandable end pocket for dirty laundry, internal mesh pockets, and an included packing cube that pulls double duty as a stuff sack, and the Alpaca strikes us as another thoughtfully built and well-equipped outdoor/travel duffel. Not everyone needs their duffel bag to pack down small, but in certain situations, it can be a really nice feature to have.

Cotopaxi has carved out a corner of the market with their spunky outdoor and travel gear, epitomized by fun colorblocking and sustainably sourced materials. I want a very large backpack for travelling for several months including camping gear (sleeping mats, tent, bag etc) and don't want to strap anything to the outside because of going on public transport a lot (where your bag gets thrown underneath.

It’s also worth noting that a 45-pound bag isn’t the easiest to get in and out of your car or up a flight of stairs. Its canyoning fastener stops sand getting in and the various mesh outer pockets help to get the sand out.

Also features an interior MOLLE panel for mounting a radio pouch, oral inflate/deflate valve, and full compression/suspension straps. At the Papillon Flight Center you'll find the largest selection on 1000sqm, from shackles up to complete ready-to-fly paragliding sets. The good news is that duffel manufacturers have gotten creative with designing bags that can be carried in a multitude of ways. And for serious outdoor and expedition use, duffels like The North Face Base Camp are made all the way up to 150 liters. Not all duffel bags come with shoulder straps, but we see them frequently on smaller capacity, travel-specific bags.Of course, the right choice also depends on how much stuff you like to bring, but we find ourselves reaching for our 55-liter Patagonia Black Hole more than any other duffel in our closet. For frequent travelers, there is a lot to be said for the convenience of a wheeled duffel, especially one that can be used as a carry-on. The roller duffel is one of those “have your cake and eat it too” scenarios for travelers wanting the ease of wheeling their bag with the packing convenience of a duffel.
