Polartec® High Loft™ is a softer, loftier fleece that combines an optimal warmth-to-weight ratio with compressibility to deliver a lightweight yet effective insulation layer for extreme conditions. Thanks to its elevated fleece design, Polartec® High Loft™ offers superior thermal insulation while remaining incredibly lightweight and breathable.

The knitted material used to make Polartec® High Loft™ is transformed into soft, versatile fleece through a series of proprietary, specialized surface-finishing techniques. The premium polyester yarns help repel moisture and speed up dry times while the lofted structures create thermal air pockets to retain warmth and still allow optimal breathability. This is why Polartec® synthetic fleece continues to be the most dependable, versatile fabric around.

How does Polartec® High Loft™ differ from other fleece fabrics? Polartec® High Loft™ features proprietary thermal air pocket technology to provide an exceptionally high warmth-to-weight ratio. By creating air pockets in the fleece itself, Polartec is able to increase the insulative properties while keeping the fabric light and compressible for easy packing and layering.

Polartec® High Loft™ uses a high pile design that traps warm air in thermal pockets, providing exceptional warmth without they bulk or weight. In fact, the design is engineered to minimize weight while maintaining the insulative properties needed for cold environments, offering a perfect balance between comfort and warmth.
