Goldwin - Star Trail Vest - Marinwood GreenThis lightweight trail running vest was co developed with Goldwin athlete and world class trail runner Dylan Bowman. With an emphasis placed on stretch, lightness, and storage capacity. The back features the main storage chamber and the material has both elasticity and a superior fit meaning it stretches well with things inside but wont shake much when running. There is also a mesh material on the back to aid breathability when you up the pace.
