A 37.5-liter duffel with ventilated shoe pockets, a wipe-clean base, and a lifetime warranty.
At 20.5 inches long and 37.5 liters, the Defender 4.0 is built like the classic gym duffel: one big main compartment, two zippered end pockets, and a reinforced base that shrugs off a wet locker-room floor. The end pockets are the shoe spots, they are ventilated, and they sit where you can reach a pair without unpacking everything else.
That layout is why this is our top pick. The bag takes a change of clothes, a towel, a water bottle, and a pair of shoes with room left for a hoodie, and it does it for less money than the two bags nearest it in quality. The water-resistant base matters more than it sounds: after a few weeks of gym floors, that is the part of a duffel that decides how long it keeps looking new.
Five compartments keep the small stuff from migrating to the bottom, and the lifetime warranty is the detail that seals it for us — zippers and straps are what end a gym bag's life, and adidas covers them. We have carried it as a plain duffel between the car and the locker, which is all most gym trips ask for.
It also doubles as a weekender. With the shoes out of the ends, 37.5 liters covers two days of clothes for most people, and the web handles are comfortable enough for the walk from the parking lot. Buy it once, use it for both jobs, and stop thinking about bags.
Bottom Line
The most complete gym bag here: 37.5 liters, ventilated shoe pockets, a wipe-clean base, and a lifetime warranty that covers the parts that usually fail.
