ULTRASPIRE - Astral 5.0 Race Vest (Black / Coral)



The Astral 5.0 is a 9-liter pack and the newest iteration of our women’s specific race vest that features the patented HerFit Harness. The HerFit Harness is a securing strap system designed specifically to fit women. The straps allow for the chest, heart, and lungs to be free with no restriction to the open air. The front harness of the Astral 5.0 has been updated to allow capacity for a variety of hydration options. This pack utilizes our UltrAcool Light Mesh which provides a very breathable and lightweight feel and increases pack durability. It is lined with a soft-perimeter binding to ensure any contact with the body is comfortable over the long haul. The shoulder pocket on the Astral 5.0 is large enough to carry any size of cell phone comfortably. For storage, the Astral 5.0 is equipped with 8 pockets allowing the ability to customize your gear needs to your race or adventure. For an even better fit, the Astral 5.0 uses our MaxO2 System side compression adjustment which helps stabilize the pack empty or fully loaded and provides a more fitted feel with less heat retention. The main compartment of this vest features an expandable mesh to store larger items and can be secured down with string compression keeping the pack stable. 2 2-liter reservoir is included.
