Made with durable, weather-resistant material, the Nike Alpha Adapt Cross Body Men's Training Duffel Bag easily converts to a cross-body shoulder bag for comfortable carrying behind your back. Custom Carry An adjustable clip and padded strap allow you to carry the bag over your shoulder or behind your back, so it stays out of the way when you're on the move. Weather Protection Weather-resistant material deflects water to help protect stored items during tough outdoor workouts—or tough daily commutes. Organised Storage Multiple compartments help keep your gear secure and organised.
