"What Our Gearhead® Experts Are Saying:""I started tossing the GOREWEAR Drive Vest into my pack on any run where the forecast was even slightly unpredictable. At two ounces it weighs practically nothing, and the WINDSTOPPER membrane genuinely cuts the wind without trapping heat, which is exactly what you want when your effort level is high and conditions keep shifting.""Some runs start calm and turn on you fast. The GOREWEAR Drive Vest is built for exactly that moment, the one where the trail crests a ridge and the wind hits you square in the chest without warning. Light enough to forget you packed it and protective enough to matter when you need it, this vest earns its place in the rotation on any run where the weather has opinions. GOREWEAR used WINDSTOPPER technology by GORE-TEX LABS for the membrane, which is totally windproof and reliably breathable so you stay comfortable at effort without overheating. The semi-transparent nylon outer layer gives it a look that stands apart from standard running kit, while highly reflective tape and logo details keep you visible when the light gets low. The whole vest stows into its own back zip pocket, so it disappears into your kit until the moment it becomes the most important thing you brought."
