Women-Specific Fit and Design.

Products that have fallen victim to the "shrink and pink" laser often fail to fit well, which is something that is of paramount concern when you're headed on a 30 mile run. However, the UltrAspire Astral 2.0 Hydration Pack is designed with a women-specific fit, assuring equal parts comfort and mobility as you cruise over varied terrain.

To start, the Astral is outfitted with a breathable, strong, yet lightweight and flexible mesh that wicks away moisture and dries quickly. Microfiber trim keeps comfort at the forefront of the fit, while the PU and silicone coatings fend off light moisture and abrasive objects. Unique to UltrAspire is the Max O2 Sternum straps, which feature a specific placement and stretch cord to assure unobstructed breathing and a stable fit—but without squishing your chest. A bevy of pocket choices allow you to keep all of your essentials, be it gels, food, or clothes close at hand, and the hydration sleeve is compatible with two liter reservoirs for adaptive performance. 

  • A women-specific hydration vest for running long distances
  • Mesh is reinforced by silicone and PU coating
  • Adjustable webbing provides a bounce-free fit
  • Bevy of pockets keep necessities close and organized
  • Compatible with a 2-liter hydration reservoir
  • Keep reservoir tube secure with magnetic clip
