The Nathan VaporAir 4.0 8 Liter Hydration Vest is a versatile running vest for long trail runs and adventures in all weather conditions. Its streamlined design combines comfort, stability, and smart storage with durable materials that stand up to heavy use.

The Quick-Fit™ adjustment system with internal wrap-around panels and visible front toggles lets you easily adjust the size while on the go. This creates a snug, stable fit that stays comfortable all day long.

The vest is made with quick-drying ripstop fabric on the back and breathable 3D mesh on the shoulders and back for maximum ventilation. For hydration, the VaporAir 4.0 comes with a 2-liter Nathan x Hydrapak hydration bladder with a quick-release hose for easy detachment and cleaning.
