Why is windproof protection so important? Consider this: With a wind speed of 20 mph, a temperature of 41ºF will feel like 17ºF - in just two minutes. Instead of being put toward your performance, all your energy will soon be focused on trying to keep your body warm. Slam the door on windchill and protect the warm but highly sensitive microclimate that surrounds your skin. WINDSTOPPER® fabrics are 100% windproof and keep you up to 2.5 times.

Lower heartbeat. Lower exertion rate. Higher average speeds. These are just three performance-boosting reasons why you should opt for highly breathable fabrics. Need more? How about this: During heavy exertion, our bodies can release over 4 cups of perspiration in an hour, and up to 17 cups during a world-class marathon. Only the most breathable fabrics can handle this much sweat to prevent you from overheating and eventually becoming chilled.

WINDSTOPPER® products are 2X more breathable than comparable windproof products, and offer the same level of breathability as comparable non-windproof products. What makes them so breathable? The 1.4 billion micropores in every square inch of the WINDSTOPPER® membrane let water vapor escape virtually unhindered, even when you're working at maximum intensity.

WINDSTOPPER® Technical Fleece provides more warmth and comfort than non-windproof fleece with less bulk by combining total windproofness and maximum breathability. WINDSTOPPER® Technical Fleece is effective as a mid-layer or outer layer, keeping you warm and comfortable in cool and windy conditions.
