Men's & Women's Bum Bags, Cross-Body Bum Bags & Belt Bags
Every athlete needs one of these. Under Armour bum bags are built to fit around your active lifestyle. Whether you’re traveling to training, want to securely carry gear while running, or need quick access to your items when hiking trails or traversing urban landscapes, our men’s and women's bum bags give you the highest quality, most durable and most reliable gear.
The toughest women’s and men’s bum bags
Bum bags should be durable, easy to access, and secure.
We made ours with incredibly tough buckle closures that clip securely into place. We used our water-resistant UA Storm technology to keep your essentials dry. And you get strong, ergonomic zippers to easily access your items. They’re also super adaptable, and can be worn as waist pack bags or over shoulder bum bags.
Waist and crossbody bum bags need to be secure - especially when you’re travelling. You’ll find tech like RFID-blocking pockets to protect against credit card theft, and zippered compartments with internal organisation to deter pickpockets.
Every feature of these bum bags has been thought through to fit better around your lifestyle. You’ll find air-mesh panels that prevent overheating, zip pockets for easy access to water bottles, or drop in pockets to quickly get to your keys, gym locker padlock or earphones.
