Under Armour Midnight Navy/ Metallic Silver Undeniable 50 LG Duffel Bag

The Under Armour Undeniable 5.0 LG Duffel Bag in Midnight Navy/Metallic Silver brings a bold, team-ready color combination to one of the most functional large-format sports bags on the market. The deep navy base paired with metallic silver accents gives this duffel a sharp, athletic appearance that works equally well for team kits, gym sessions, and weekend travel.

Built from 100% polyester with UA Storm technology, this bag delivers a highly water-resistant finish that guards your gear against rain, splashes, and wet surfaces during your daily commute or post-game transport. Tough, abrasion-resistant bottom and side panels reinforce the bag at its highest-wear points, extending its useful life across hundreds of training sessions and road trips.

The Midnight Navy/Metallic Silver version of the Undeniable 5.0 LG carries the same thoughtful internal organization as the full lineup. Two large front zippered pockets handle quick-access items like your phone, wallet, headphones, and keys. A large vented pocket isolates wet laundry, muddy cleats, or post-swim gear from your clean clothes, keeping everything fresh and odor-free.

Internal slip pockets round out the organization options for flat or thin items. Carrying is made easier by the removable, padded HeatGear shoulder strap that cushions load on long hauls, and the padded top grab handle provides a secondary carry option for short distances.

The embroidered UA label on the side and the heat-seal UA logo on the front complete the look. At 29.5 x 14.5 x 14.1 inches, this large duffel is sized right for athletes who never travel light.
