Fit:<\/strong> \u00a0Unisex The Big Bronco Race Vest is a 12 liter pack built in collaboration with UltrAspire Elite Athlete and champion ultramarathoner Jeff Browning. The Big Bronco is designed to highlight all of the features of the Bronco race vest but with expanded capacity and accessibility. This vest has a total of 7 accessible pockets on the go, and is capable of carrying 4 bottles and a 2 liter reservoir. While two of those bottles can be stored in front , our signature bottle-in-the-back Fluidic Holster System ensures access to the rear pockets is intuitive and easy. The rear pockets have a divider which helps to organize your gear and 2 large gussets add capacity. The main back compartment was designed to lay flat when empty while its 4-way stretch mesh can expand to accommodate a large capacity. A soft foam flare on the back serves as a guide, making rear compartment access easy. Z-pole attachments have been added and are accessible left or right handed on the go, and these attachments can also function as compression for the Fluidic Holster compartments. The front harness features 4 pockets and the MaxO2 Form adjustable closure system. Like all UltrAspire packs, this vest features an ErgoFit™ design for long term comfort. Available in 3 sizes.<\/p>\n
