Polartec® Power Dry® fabrics are designed to keep your skin dry when you sweat. All fabrics in this series feature a patented bi-component knit construction that uses different yarns on either side of the fabric. This creates two different surfaces: one that is optimized to move moisture away from the skin, the other to dry quickly.

Polartec® 100 Micro Fabrics are the reference standard for lightweight warmth and breathability. Tight-knit construction features 100% polyester microfibers and dries quickly. These durable, non-pilling fabrics maintain their insulating ability after repeated laundering. 100 Micro fabrics keep you warm and comfortable in a wide range of conditions.

Polartec® Power Stretch® fabrics feature body-hugging 4-way stretch and are very breathable. These are the most versatile outdoor apparel fabrics available today. The proprietary construction features two unique surfaces: the durable nylon outer layer is wind - and abrasion - resistant; the soft polyester velour inner layer is warm and comfortable.

These fabrics are available in a range of weights to provide the right level of insulation for most outdoor activities. Classic 100™ fabrics are the lightest weight and are excellent for a warm first layer or lightweight sweater. Classic 300™ fabrics are the heaviest and provide a warm thermal layer for very cold outdoor activities. Halfway in between are Classic 200™ fabrics, providing outstanding warmth and versatility.

Polartec® Windbloc® fabrics block 100% of the wind and offer maximum protection from the cold and the elements. They combine the warmth of Polartec® thermal fabrics with a polyurethane barrier membrane that allows moisture vapor transmission and is completely windproof and waterproof, eliminating the need for a windbreaker or additional shell.This reduces the weight and number of layers needed to protect and insulate. These fabrics are very durable, quiet, and non-pilling, and have enhanced stretch and recovery, making them appropriate for general outerwear and accessories where weather protection is desirable. Windbloc® fabrics are ideal when the activity level is low or intermittent, and when cold and inclement weather demands high-performance outer protection.
