UA Storm Technology

A proprietary DWR-style treatment bonds to the fabric at a molecular level, causing water to bead and roll off the surface rather than soaking in. Whether you are heading through a drizzle on the way to the gym or caught in a sudden downpour after practice, UA Storm keeps the contents of your bag dry without adding any noticeable weight to the bag itself.

Total Organisation System

The spacious front zippered pocket features MOLLE webbing attachment points so you can clip on pouches or accessories as needed. Internal slip pockets in the main compartment keep smaller items — keys, cards, earphones — instantly accessible and separate from clothing or shoes.

Side Mesh Slip Pocket

A dedicated side mesh pocket gives you fast access to a water bottle, recovery drink, or any item you want to reach without opening the main compartment. The open-mesh construction provides light ventilation and lets you see what is stored at a glance.

Vented Shoe and Laundry Pocket

The large vented pocket at the base is specifically designed to isolate footwear or post-workout laundry from the rest of your gear. The ventilation panel allows airflow so damp clothing or worn shoes can breathe, reducing moisture build-up and helping the bag's built-in odour control technology do its job effectively.
