Created in collaboration with our trail running athletes, Flight Series" takes you longer, stronger. And to ensure the ride is as smooth as possible, we developed the Race Day Vest. It provides just enough space for storing the things you need water, gels, a shell layer, phone and other race-day safety gear without extra weight, which you certainly don't need when going the distance. The durable, ripstop fabric is sweat-wicking and highly breathable. The front fastening system is fuss-free and easy to adjust on the go. The two soft water bottles included can be attached to the bottle pockets via a leash system, which enables quick re-loading, even when the water bottles are empty.
