Trusted on more hunts than any other vest we make, the Jetstream Vest is a rugged windproof workhorse that shields you from the elements without slowing you down. WINDSTOPPER(R) by GORE-TEX LABS completely blocks heat-sapping winds, but is still breathable to keep you from getting bogged down with sweat on uphill assaults. We also outfitted it with a tough softshell fabric with reinforced panels in key areas to help it stand up to the thickest brush and roughest rock.
