The award-winning VaporAiress 7L 2.0 running vest has an adjustable sizing system that ensures a proper fit for a broad range of runners and includes a full 2 liters of at-the-ready hydration as well as convenient storage for other items.
The pack's body-mapped backpanel is constructed of breathable, moisture-wicking mesh. The soft materials and chafe-free edging makes for a comfortable, worry-free carry. The pack comes in two sizes each of which has an Adaptive-Fit system to provide customizable micro adjustments. Measurements are based on the circumference of your chest at the sternum and also at the bust. The smaller of the two sizes best fits a sternum measurement of 26"-33" and a bust measurement of 30"-36" while the larger size best fits to 33"-41" at the sternum and 37"-44" at the bust.
A rear compartment houses the included 2.0L hydration system. A long drinking tube with an integrated bite valve provides on-the-go hydration and a quick release valve makes for convenient refilling and cleaning of the reservoir. A sternum attachment point on the front of the pack holds the drinking hose securely in place. Additional rear storage includes a large, zippered compartment and a kangaroo pocket for items you want to quickly put hands on. Multiple front harness pockets keep smaller essentials in close reach. There are both zippered and open stretch pockets so you can determine what needs the most secure storage and what needs to be ready at a moment's notice. Other features include trekking pole attachment points (poles not included) and 360 degree reflectivity.
