With female trail runners and endurance racers top of mind, the UltrAspire Astral 4.0 Women's running vest delivers a snug, movement-mirroring fit without pinching high across the chest like many men's or unisex running packs. A 2L hydration system is included to keep water at the ready.
Flexible and durable mono mesh fabric maximizes breathability and next-to-skin comfort. Soft perimeter polyester fabrics further enhance comfort. The HerFit harness has angled shoulder straps to reduce neck and shoulder fatigue, and contours lower on the body for a lower center of gravity and increased pack stability. Stretch hook-and-pull front straps and side compression adjustment allow you to fine tune fit and eliminate "bounce" without feeling constricted.
A lined, insulated sleeve 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.
In addition to the hydration sleeve, the pack has a large zippered main compartment with expandable mesh that has a capacity of up to 9 liters. If the full capacity isn't needed, a string compression system keeps the pack compact and stable. Compression straps running across the back of the pack keep contents secure and expand to let you lash gear externally. Harness pockets offer intuitive gear placement, including a large cell phone pocket and a sweat-proof pocket for items you want to keep dry.
