The Bronco Race Vest was built in collaboration with UltrAspire Elite Athlete and champion ultramarathoner Jeff Browning. The Bronco has a 5 liter capacity and a pocket configuration ready to carry a variety of hydration options including a 1 liter reservoir. The front harness features 4 pockets that are built from 4-way stretch mesh. Our patent pending MaxO2 Form closure secures the pack’s contents and adapts to your body shape with a single pull. The side pockets, or saddlebags, provide access to your gear quickly. These pockets offer massive capacity with an elastic closure which keeps the contents stable. The main back compartment was designed to lay flat when empty while the 4-way stretch mesh accommodates a large capacity. The UltrAcool Light Mesh on the back panel eliminates any discomfort when fully loaded. Accessing the back compartment is made easier by a soft foam flare which extends up, guiding your hands into position. The back panel also houses a sweat proof pocket. In total, the Bronco has 7 pockets accessible on-the-go. Like all UltrAspire packs, this vest features an ErgoFit design for long term comfort. Available in 3 sizes.
