Coreloft™ is a synthetic non-woven insulation. Durable, resilient and lightweight, Coreloft™ dries quickly, retains warmth when wet and is easy care.

Coreloft™ can be found in many Arc'teryx insulated products.

Polyester staple fibres of mixed sizes are crimped to trap air and retain warmth. Large denier fibres resist compaction and allow the use of looser weave face and lining fabrics, increasing overall air permeability.

The hydrophobic nature of Coreloft™ keeps you insulated in wet or damp conditions. Excellent long term resilience and loft recovery increase the longevity of Coreloft™ insulated garments, making it a solid all around insulation choice.
