Polartec: Windbloc
Polartec® Windbloc® blocks 100% of the wind and offers maximum protection from the cold and the elements, reducing the weight and number of layers needed to protect and insulate.
Imagine combining the warmth of Polartec® fleece with a windproof/water-resistant breathable barrier, eliminating the need for a windbreaker or additional shell! Two fleece layers, one Hydrophilic and one Hydrophobic. (That's techno terminology for a love/hate relationship to water.) The urethane membrane that joins the two stays soft.
Maximum weather protection, comfort, and breathability.
