The bag features multiple compartments including a large front pocket, a vented section for laundry or shoes, and internal slip pockets to keep smaller items organized.

It offers flexible carrying options with a removable, padded shoulder strap and a padded grab handle, making it easy to carry in different ways. The materials used, such as TPU-coated and foam-lined panels, give the bag added toughness and structure, helping it hold up well over time. The UA Storm technology adds a water-repellent finish, so your belongings get some protection from rain or splashes, though it’s not fully waterproof.
