The UA Ozsee Sackpack is one of Under Armour's most iconic bags — so beloved that Under Armour used the very same design for the shopping bags in many of their retail stores. Lightweight, compact, and built to handle daily abuse, it is the perfect grab-and-go companion whether you are heading to the gym, training on the field, or just running errands. Designed for both men and women, this versatile sackpack keeps your essentials secure, dry, and within reach at all times.
UA Storm is Under Armour's proprietary DWR (durable water repellent) finish applied directly to the outer fabric of the sackpack. The treatment causes water to bead up and roll off the surface rather than soaking in, keeping your belongings dry during light rain, gym-bag toss-ins, or unexpected splashes. Unlike a fully waterproof shell, UA Storm maintains the bag's breathability and lightweight feel, so you get protection without bulk. It is an ideal feature for athletes who move between outdoor training and indoor facilities in all weather conditions.
Constructed entirely from tough, high-tenacity polyester, the UA Ozsee Sackpack is engineered to absorb the punishment of daily life. The fabric resists abrasion from gym floors, locker hooks, and rough surfaces, retaining its structural integrity through countless sessions. Polyester's inherent resistance to stretching and shrinking means the bag holds its shape over time, even when loaded to capacity. The material is also easy to spot-clean, making maintenance simple after muddy training sessions or dusty travel days.
The sackpack's closure system uses a strong, easy-cinch drawcord that simultaneously functions as the shoulder-carry straps. With a simple pull, the bag seals shut and the cords tighten to your preferred shoulder width, giving you a snug, custom fit without buckles or complex adjustment systems. The cord material is thick and reinforced at stress points, preventing fraying even with heavy daily use. This design keeps the overall weight of the bag minimal while providing all the carrying comfort you need for the gym, commute, or a day trip.
A built-in sternum clip connects the two shoulder cords across your chest, preventing the bag from swinging or slipping during runs, rides, or high-intensity workouts. This small but critical detail transforms the sackpack from a casual tote into a secure performance carrier. In addition, a dedicated zippered front pocket keeps smaller valuables — keys, cards, a phone, or earbuds — completely separated from the main compartment and safe from accidental spills. Together, these two features deliver the security and stability needed for active everyday use.
