VaporAiress 4.0 8 Liter Hydration Vest
An all-conditions, multi-size running vest featuring a streamlined design and the QuickFit™ adjustment system, which wraps around the torso and tightens or loosens easily via exposed front toggles.
Inspired by trail runners, the next-generation VaporAiress delivers a secure, customizable women's fit with streamlined storage and rugged, quick-drying materials. A new internal wrap panel and front toggles make on-the-go size adjustment easy, ensuring all-day comfort on long runs.
Adjustable Fit
Interior wrap-around panel with exposed front toggles allows fast, secure size adjustments for a dialed-in fit.
Performance Materials
Durable ripstop fabric on the back dries quickly; 3D mesh on the shoulders and interior back maximizes airflow and breathability.

Four front expandable mesh pockets (top pockets with elastic cords to secure flasks), one interior zip pocket for valuables, 2 side mesh pockets with passthrough features, a rear main compartment with bladder sleeve, exterior bungee for extra gear, and pole keepers on the lower back.
