A gym backpack lives a harder life than a normal one — wet towels, damp kit, and shoes that have been on a gym floor all go in the same bag as clean clothes. This one separates them: a dedicated shoe compartment and a wet pocket keep the problem items isolated.
The waterproof shell means the bag wipes clean rather than absorbing whatever leaks inside it, and the lightweight build keeps the empty weight low so more of what you're carrying is actually your gear.
Large enough for a full change of clothes, shoes, and a laptop, which makes it work as a commuter bag on gym days rather than needing two bags. Suited to training, travel, and everyday carry.
