The award-winning Alpha series is the pinnacle of design, functionality, and comfort. Building on the ErgoFit design and expanding on successes of the previous iterations, the Alpha 6.0 focuses on past design strengths while introducing new functional changes. This 8-liter race vest has 9 pockets accessible on the go with 8 of them being on the front of the harness. The Alpha 6.0 highlights the benefits of a traditional fitting race vest, with improvements across the board. Most notably, the fit of the vest all around is streamlined to sit close to the body while not restricting your movements or breathing in any way. The ergonomically placed rear passage pocket makes accessing items stored in the back of the pack quick and easy. The MaxO2™ Sternum, proprietary to UltrAspire, keeps the Alpha 6.0 secured and hindrance-free while running. Compatible with a range of hydration options and available in 3 sizes to ensure a perfect fit.
