The Under Armour Undeniable 5.0 Medium Duffle Bag is a versatile sports bag designed to keep up with your active lifestyle — whether you are heading to the gym, travelling for a tournament, or packing for a weekend trip. Part of the well-established UA Undeniable series, this updated medium-sized duffel combines a lightweight build with exceptionally durable materials engineered for long-term use. The UA Storm water-repellent finish adds an extra layer of weather protection, keeping your gear dry whatever the conditions.
UA Storm is Under Armour's proprietary DWR (durable water repellent) treatment applied directly to the fabric. It causes water to bead up and roll off the surface rather than soaking through, protecting your belongings from rain, splashes, and damp surfaces. The technology does not compromise breathability, meaning the bag stays fresh even when packed with post-workout kit. It is a proven system across the UA Undeniable line and holds up through repeated use without significant degradation.
The base and side panels are constructed from a rigid, foam-backed thermoplastic polyurethane (TPU) material. This gives the bag a structured shape so it stands upright on its own, protecting the contents from impact and abrasion when placed on wet or rough surfaces. The TPU coating is resistant to scuffs and scratches, making it ideal for gym floors, car boots, and overhead lockers alike. This reinforcement is one of the key reasons the Undeniable series has remained a go-to training bag for athletes over many years.
The Undeniable 5.0 Medium features a thoughtfully designed interior layout that makes it easy to keep your gear sorted. A large vented pocket separates dirty laundry or shoes from clean clothing, preventing odours and moisture from spreading. Smaller internal pockets provide dedicated storage for keys, cards, headphones, and other everyday essentials. The dual water-bottle pockets on the exterior ensure hydration is always within arm's reach without having to open the main compartment.
MOLLE (Modular Lightweight Load-carrying Equipment) webbing on the exterior allows you to attach additional pouches or accessories, giving the bag a modular, customisable carry solution. The large front zip pocket provides quick-access storage for items you need frequently during your session — phone, wallet, gym pass, or snack. Combined with the removable padded shoulder strap (which tucks away into a side pocket when not in use) and the padded top handle, the bag offers flexible carrying options to suit every situation.
