Most gym bags can be cleaned by wiping the exterior with a damp cloth and mild soap. For the interior, check the care label—some bags are machine washable, but others may need spot cleaning. Air drying is essential to avoid damage. Regularly empty and air out your bag to prevent odors and keep it fresh.

Duffel-style gym bags are especially popular for overnight trips, while backpack-style gym bags work well for commuting.

The right size depends on how much gear you carry. If you need space for shoes, clothes, toiletries, and gym equipment, opt for a larger duffel bag. For lighter loads, a medium-sized bag or backpack is ideal. Make sure to consider locker space at your gym if you plan to store it there during workouts.
