About WINDSTOPPER

Get more from your outdoor experience. WINDSTOPPER® fabrics are engineered for peak performance and total comfort, even in wind, light rain or snow. Pushing yourself harder - or just taking it easy - has never felt so good.

WINDSTOPPER® fabrics are constructed by laminating our special membrane to a wide range of functional fabrics selected according to the final product's intended use.

Every square inch of the WINDSTOPPER® membrane contains 1.4 billion micropores. This revolutionary structure is ultra-light, ultra-thin, and highly resistant to extreme temperatures. The microporous structure of the WINDSTOPPER® membrane ensures maximum breathability; cold wind is kept out, but moisture vapor can easily escape.

Integrated into the ePTFE portion of the membrane is a hydrophobic, or water-hating, substance to keep external moisture away from your skin. This thermoregulating effect keeps you comfortable longer, so you can be at your best.

"Dress for the occasion." Forget fashion rules, we're talking about achieving optimum climate control based on your intended activity, level of intensity, and environment. That's why we engineer different WINDSTOPPER® laminates for a wide range of activities and weather conditions.

To construct a WINDSTOPPER® laminate, the ePTFE (expanded polytetrafluorethylene) membrane is bonded to a wide range of high-performance fabrics. Depending on the application, a variety of outer fabrics and lining materials are used to create 2-, 3- and even 4-layer constructions.

More comfort equals better performance. Yes, it really is that simple. Just ask any professional athlete.
WINDSTOPPER® fabrics offer soft, lightweight weather protection in one versatile and durable garment. Owing to their total windproofness and maximum breathability, our garments will keep you comfortable longer across a wide range of weather conditions and activities.

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.
