The award-winning UltrAspire Alpha 2.0 running vest is a favorite of performance-demanding ultra runners. Despite weighing just 11.9 ounces (weight includes the included 2L reservoir), the pack has ample storage, great organization, and an absolutely dialed fit.
The broad, honey-combed mesh fabric of the Alpha 2.0 maximizes breathability and next-to-skin comfort. Soft perimeter polyester fabrics further enhance comfort. Dual patent-pending hook-and-pull chest straps allow you to fine tune fit and eliminate “bounce”.
A large stretch pocket on the back of the pack houses the included 2L hydration system. A broad opening and simple hanging system make it easy to get the reservoir in and out of the pocket. The drinking tube can easily be run over either shoulder.
Other pockets include two stretch lateral pockets that are positioned to allow on-the-go access, two large mesh pockets on the front harness that are capable of hauling 22 oz water bottles (not included), a small zippered pocket, and a water-resistant, magnet-closure pocket that is perfect for stowing electrolytes. There is also a bungee gear attachment system on the back of the pack and reflectivity on both sides of the pack.
The UltrAspire Alpha 2.0 running vest is available in Black Small (best fits chests measuring 26”-35”), Steep Green Medium (32”-38”), and Red Large (38”-46”) color/size options. With apologies, each size is only available in the noted color.
