Arc'teryx Alpha Insulated Pant is a down-insulated trouser that keeps you warm and comfortable even in relentless winter cold. It is insulated with RDS-certified goose down rated at 850 fill power, delivering outstanding warmth, and is supplemented with synthetic insulation in areas particularly exposed to moisture.

The outer fabric consists of an ultralight and ultra-durable Hadron™ material that keeps wind and water at bay, complemented by a highly breathable 2-layer GORE-TEX INFINIUM™ membrane.

The trouser has a regular fit with an anatomical design that ensures good freedom of movement. Additional features include full-length side zip openings for easy on and off, a zip thigh pocket accessible while wearing a harness, an elasticated waist with internal adjustment, and a hem adjustment that keeps debris and snow out. Supplied with a stuff sack.

This is a unisex product based on a standard men's fit. If you require a women's size, we recommend sizing down one size.
