When whipping winds barrel down on your afternoon training ride, it pays to be wearing the Gore Wear Men's Windstopper Base Layer Sleeveless Shirt underneath your jersey. Not only does this sleeveless base layer actively wick moisture and regulate body temperature, but the Gore WindStopper membrane provides a windproof barrier along zones sensitive to heat loss, such as the front torso, shoulders, and kidney area. Not only does Gore Windstopper provide windproof protection, but it's also resistant to light rain and breathes well, meaning this base layer won't soak up excess moisture or leave you feeling sweaty underneath. This WindStopper membrane sits alongside breathable stretch panels along the sides and back, which keep you moving fluidly and expel excess perspiration during spirited training rides.
