Polartec Windbloc


Polartec® Windbloc® fabrics block 100% of the wind and offer maximum protection from the cold and the elements.  A soft hand, stretch, and a durable water repellent finish (DWR) make this the highest quality, most comfortable windproof fleece product on the market.

How Does It Work?

Polartec® Windbloc® fabrics 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.

Polartec® Windbloc® fabrics are ideal when the activity level is low or intermittent, and when cold and inclement weather demands high-performance outer protection.
