Bellroy emphasized both lightweight construction and functional form in their Lite 30L Duffel Bag. The ripstop shell is made with recycled PET for a lessened environmental impact in a diamond weave that's three times lighter than the brand's alternative fabrics. Its minimal mass doesn't impact its performance, however. It's as tough as any reliable ripstop, packed with pockets for easy organization, and just the right size for a quick trip by car or plane.
