At 20.5 inches long, 11 wide and 11.75 tall, the adidas Defender is the size most gym-goers should start with. A change of clothes, a towel, a wash bag and a pair of trainers go in without a fight, and the trainers drop into one of the two zippered end pockets rather than landing on top of everything else. The water-resistant base turned out to be the detail we valued most: that is the part of the bag that touches a changing-room floor.
Five compartments are what separate it from the cheaper bags here. The main body opens wide along the top, the end pockets hold shoes or a damp towel away from clean clothes, and there is enough structure that the bag stands up when you set it down half full. We also like that adidas backs it with a lifetime warranty, the longest coverage in this group, on a bag that sits mid-pack on price.
What it does not give you is a sealed home for soaked kit, the way the Fitgriff does, so a swimmer should start there instead. For everyone else the Defender does the most without asking anything of you: no proprietary strap, no plastic shell, just a wide opening, five pockets and a base that ignores a wet floor.
Bottom line: We recommend it to most people who ask: 37.5 liters, five compartments, a base that shrugs off wet floors, and a lifetime warranty.
