UltrAspire Big Bronco Race Vest

The Big Bronco Race Vest is a 12-liter backpack developed in collaboration with UltrAspire elite athlete and ultramarathon champion Jeff Browning. The Big Bronco is designed to highlight all the features of the Bronco race vest, but with increased capacity and accessibility. This vest has a total of 7 accessible pockets and can hold 4 bottles as well as a 2-liter hydration bladder. While two of these bottles can be stored in the front, the signature Bottle-in-the-Back Fluidic Holster System ensures that access to the rear pockets is intuitive and easy. The rear pockets are equipped with a divider that facilitates gear organization, and 2 large gussets increase capacity. The main compartment at the back is designed to lay flat when empty, and its 4-way stretch mesh can expand to accommodate a large volume. A soft foam strip on the back serves as a guide and makes accessing the rear compartment easier. Z-Pole attachments have been added, which are accessible for both left- and right-handed users. These attachments can also be used as compression for the Fluidic Holster pockets. The front strap features 4 pockets and the adjustable MaxO2 Form closure system. Like all UltrAspire backpacks, this vest also has an ErgoFit design for long-term comfort. Available in 3 sizes.

Recommended use:
Versatile backpack for any running scenario, training, or race.
