Protection.

Weather protection fabrics are designed to help block wind and rain while still allowing moisture vapor to escape, so you stay protected without overheating during activity. <br> <br> Polartec weather protection options include <a href="https://www.polartec.com/fabrics/weather-protection/aircore">Polartec® AirCore™</a> for breathable water resistance, <a href="https://www.polartec.com/fabrics/weather-protection/windbloc">Polartec® Windbloc™</a> for windproof protection, and <a href="https://www.polartec.com/fabrics/weather-protection/power-shield-rpm">Polartec® Power Shield™ RPM</a> for breathable, windproof, and water resistant* performance with comfortable stretch. <br> <br> *10k mm water resistance (ISO 811)/20k g/m²/24hrs breathability (JIS L1099, B1)

The best option for blocking wind is a windproof fabric designed to stop cold air from coming through while still allowing breathable comfort and movement. <br> <br> <a href="https://www.polartec.com/fabrics/weather-protection/windbloc">Polartec® Windbloc™</a> is built for this kind of wind protection. It blocks wind, repels light moisture, and adds breathable stretch, making it a strong choice for cold, windy conditions. <br> <br> For high-output activities where breathability is as important as wind protection, <a href="https://www.polartec.com/fabrics/weather-protection/aircore">Polartec® AirCore™</a> is another strong option because it helps protect against wind while allowing moisture vapor to escape.

Windproof fleece is a type of performance fleece designed to reduce wind chill while providing warmth and breathability. It is used when standard fleece feels too exposed in windy or variable conditions. <br> <br> <a href="https://www.polartec.com/fabrics/insulation/wind-pro">Polartec® Wind Pro™</a> offers greater wind resistance than regular synthetic fleece while staying breathable, durable, and water repellent. <a href="https://www.polartec.com/fabrics/flame-resistant/wind-pro-flame-resistant">Polartec® Wind Pro™ FR</a> provides similar wind resistant performance with flame resistant protection for more specialized environments.

Wind resistant fabrics help reduce wind penetration, but some air can still pass through. Windproof fabrics are built to block wind more completely. <br> <br> <a href="https://www.polartec.com/fabrics/insulation/wind-pro">Polartec® Wind Pro™</a> is wind resistant, making it a strong option when you want wind protection with high breathability. For windproof protection, <a href="https://www.polartec.com/fabrics/weather-protection/windbloc">Polartec® Windbloc™</a> uses a barrier membrane that blocks wind while providing full comfort in cold, windy conditions.

A good windbreaker material should block or reduce wind while still feeling breathable and easy to move in. It should also offer water repellency, durability, and enough stretch for layering or active use. <br> <br> For breathable wind resistance, <a href="https://www.polartec.com/fabrics/insulation/wind-pro">Polartec® Wind Pro™</a> is a strong option. For more complete windproof protection, <a href="https://www.polartec.com/fabrics/weather-protection/windbloc">Polartec® Windbloc™</a> is built to block wind while maintaining comfort and stretch. For higher output conditions, <a href="https://www.polartec.com/fabrics/weather-protection/aircore">Polartec® AirCore™</a> adds strong breathability with weather protection.

For wet and windy conditions, <a href="https://www.polartec.com/fabrics/weather-protection/power-shield-pro">Polartec® Power Shield™ Pro </a>is the strongest choice. It provides waterproof, breathable protection for harsh weather while helping manage heat and moisture during activity. This helps keep you dry and comfortable without overheating. <br> <br> For lighter weather protection, <a href="https://www.polartec.com/fabrics/weather-protection/windbloc">Polartec® Windbloc™</a> offers windproof, water resistant performance with breathable stretch. Whereas <a href="https://www.polartec.com/fabrics/insulation/wind-pro">Polartec® Wind Pro™</a> is better for wind resistance and light moisture, but not is not suited for sustained wet weather on its own.

Water resistant fabrics shed light rain or snow, but do not offer a complete barrier against moisture. They work best for mildly inclement weather or active use where breathability matters. <br> <br> A waterproof fabric is built to block water more completely in sustained wet conditions. <a href="https://www.polartec.com/fabrics/weather-protection/power-shield-pro">Polartec® Power Shield™ Pro</a> is designed for waterproof, breathable protection, while fabrics like <a href="https://www.polartec.com/fabrics/insulation/wind-pro">Polartec® Wind Pro™</a> offer water repellency for lighter moisture.
