High Loft™

It shouldn't be a challenge to pack light and stay warm.

Polartec® High Loft™ was created to expand and enhance the performance benefits and design applications of fleece technologies. By utilizing a high loft fiber construction we developed a stunningly soft and fluffy structure that compresses to pack easily in small spaces. Large air pockets created by the extended fibers retain optimal warmth to provide the highest warmth to weight ratio of any thermal fleece fabric available today.

  • Warmth without weight
  • Highly breathable
  • Packable
  • Fast drying
  • Easy care
  • Various styles + weights avaliable
Best Uses
  • Compressible weather resistant insulation

Ever since we invented the original synthetic fleece we have been committed to pushing the technological boundaries of the material. Polartec® High Loft™ is a reengineered approach to polyester yarn construction that increase thermal warmth retention and decreases overall fabric weight.

The lofted fibers create large air pockets for retaining optimal body warmth and releasing excess heat for enhanced breathability during activities. This fluffy structure also reduces surface friction for comfortable layering with other materials.


The naturally hydrophobic properties of Polartec® High Loft™ fleece repel moisture when exposed to the elements and speed up dry times. Reducing the absorbency of fabric ensures it remains lightweight and breathable, even in the most challenging environments and ever changing weather conditions.

Open mesh stitching regulates airflow and breathability during exertion for increased comfort. This durable construction allows the fabric to retain its lofted form, even after heavy use and multiple trips through the washing machine.
