The Under Armour Undeniable 5.0 Small Duffle Bag in black is the ideal companion for the gym, travel, and every active day in between. Built on the trusted legacy of the UA Undeniable line, this updated 5.0 version is lightweight yet constructed from incredibly durable materials designed to last for years of hard use. A highly water-repellent UA Storm finish keeps your gear protected from the elements, while a structured TPU-coated bottom and side panels ensure the bag holds its shape no matter what you throw at it. With a generous 40-litre capacity, dedicated ventilated storage, and smart pocket organisation, this is the sport bag that covers every base.
UA Storm is Under Armour's signature surface treatment that bonds a highly water-repellent finish directly to the fabric fibres. Rather than adding a heavy waterproof membrane, the technology allows the bag to remain lightweight while actively shedding rain, splashes, and damp conditions. The result is a bag that keeps your gear dry in everyday weather without sacrificing breathability or flexibility. Whether you are heading from the car park to the gym in a downpour or packing kit for an outdoor training day, UA Storm has you covered.
The bottom and side panels of the Undeniable 5.0 Small are reinforced with a tough polyurethane (TPU) coating over a foam-lined interior layer. This construction gives the bag a rigid, protective shell at its most vulnerable points — the areas most likely to be dragged, dropped, or scraped. The foam lining adds cushioning for delicate items stored near the base, while the TPU outer layer resists abrasion and moisture penetration. The combined effect is a bag that holds its shape, protects your gear, and stands upright on any surface.
The dedicated vented side pocket is one of the Undeniable 5.0's standout organisational features. Designed to separate wet, dirty, or odorous items from your clean gear, it is large enough to accommodate a pair of training shoes or post-workout laundry. The vented construction allows airflow to circulate around the contents, helping to manage moisture and reduce odour build-up. This prevents the rest of the bag from picking up unwanted smells — keeping your clean kit genuinely clean even after a hard session.
The large front-facing zippered pocket offers a dedicated zone for everything you want close at hand — phone, keys, wallet, energy gels, or a light layer. Inside the pocket, internal slip pockets allow further sorting so nothing ends up loose at the bottom. The exterior of the bag also features Molle (Modular Lightweight Load-carrying Equipment) webbing attachment points, a feature borrowed from tactical gear design. These allow you to customise your carry by clipping on additional pouches, carabiners, or accessories to expand the bag's functionality to suit your activity.
Staying hydrated during training is non-negotiable, and the Undeniable 5.0 Small makes it effortless with twin dedicated water bottle slip pockets. Positioned on the exterior for instant access without opening the main compartment, they accommodate standard sports bottles and are elasticated to hold contents securely even when the bag is in motion. Whether you carry a single bottle or prefer to have a recovery drink on one side and water on the other, the dual pocket configuration has you covered without consuming any space inside the main body of the bag.
The Undeniable 5.0 Small ships with a removable, padded shoulder strap built with Under Armour's HeatGear® material — a moisture-wicking fabric engineered to stay cool and comfortable against skin. The strap is fully adjustable to suit your height and preferred carry position and features padding at the shoulder point to reduce pressure during longer carries. When you prefer to carry the bag by its padded top grab handle — or when packing it into a locker — the shoulder strap detaches quickly and stows compactly in the side pocket, keeping everything tidy.
