The lightest Vapor vest to date, the Nathan VaporAir keeps water and gear close to the body to prevent bouncing and maximize comfort while running or racing.  A 70 oz (2L) slideseal bladder with magnetically-held hydration tube offers the hydration you need, and a back stash pocket provides gear or apparel storage for those long trail runs.  Dual front holsters give you access to two 22 oz bottles for additional hydration, while 2 stretch mesh side pockets and one front zipper pocket can fit small essentials or a smartphone (including iPhone 6).  A breathable mesh back and shoulder straps make for a comfortable fit as you take to the trails.
