The award-winning UltrAspire Alpha 3.0 running vest is a favorite of performance-demanding ultra runners. Despite weighing just 12.2 ounces (weight includes two included water bottles), the pack has ample storage, great organization, and an absolutely dialed fit.
The broad, honey-combed mesh fabric of the pack maximizes breathability and next-to-skin comfort. Soft perimeter polyester fabrics further enhance comfort. Dual hook-and-pull chest straps allow you to fine tune fit and eliminate “bounce”. The pack is available in Small (best fits chest sizes of 26”-35”), Medium (32”-38”), and Large (38”-46”) size options.
A large stretch pocket on the back of the pack has a 350 cubic inch storage capacity and is capable of housing a hydration system (sold separately). Other pockets include two stretch lateral pockets that are positioned to allow on-the-go access, a small zippered harness pocket, a water-resistant magnet-closure pocket that is perfect for stowing electrolytes, and two stretch mesh harness pockets. The stretch pockets are ideal for carrying the two included UltraFlask 550 water bottles. The soft, ergonomic bottles fit comfortably against your chest and boast high-flow drink-through caps. The pack also has a bungee-corded gear attachment system and reflectivity hits that provide low-light visibility.
