Regular price$700.00


The Alpha Insulated Pants from Arc'teryx are lightweight and extremely warm expedition hybrid 850 fill goose down and synthetic Coreloft™ insulated pants with fully separating side zippers and seam-taped extremely lightweight and strong 2-layer GORE-TEX® INFINIUM™ Hadron™ proprietary outer face fabric that is engineered with a liquid crystal polymer ripstop that makes this fabric as abrasion resistant as many other fabrics twice the weight.  The GORE-TEX® INFINIUM™ fabrics also block the wind while trapping and holding in more warmth than standard fabrics.  Other features include a belay loop compatible fly, harness accessible zippered thigh pocket, and hem adjusters to seal out snow and debris.  Designed for extremely cold bivouacs and alpine belays.
