We Tested Duffel Bags for Weeks. These Are Our Favorites

This is not a true duffel bag so much as “the world’s first true wide-mouth packing system,” as Rux calls it, but it is nevertheless an impressive piece of equipment from a company known for its modular gear-toting systems. Not unlike a foldable version of the popular 70L storage container, the Duffel box starts completely flat, but the sides pop up, and the patent-pending top rolls down to form a box that stays open on its own. There are no zippers involved in its construction, but there are multiple straps, panels, and pockets, and you will most likely need to watch an instructional YouTube video to make full use of all the features. However, the beauty of this bag is that it can be just about anything you want it to be. Long-term storage, luggage, a gear box—even a backpack. All is possible with the included straps and dividers in the right places.

Over the past four months, my family has used it as a traditional duffel bag, a storage box, and, currently, a portable equipment organizer for my son’s club soccer team. It’s been stepped on, rained on, and thrown in wagons and vehicle trunks, with nary a scratch on the 105D nylon gridstop fabric. (Though it did get stuck in a downpour once, and I will say I’m not sure I’d quantify the fabric as fully waterproof—closer to water resistant.) Lash points along the inside walls allow it to integrate with Rux’s line of accessories and packing bags (sold separately), in which we’re currently keeping pinnies and goalkeeper gear.

The Duffel Box will be officially for sale on March 16 in two sizes, 55L and 75L; pictured is the 55L. Note that a “Plus” version will include a removable universal shoulder strap, which connects to lash points on the outside, for an extra $25. —Kat Merck
