Belaying in winter is a frigid task. Our warmest down-filled belay jacket, the Alpha Parka, keeps the cold and wind at bay so you can focus on belaying. The extraordinary warmth of 850 fill RDS-certified down is complemented by hollow fiber in strategic places to improve breathability in moisture-prone areas.

The exceptionally breathable GORE-TEX INFINIUM™ 2L with ultra-light and ultra-durable Hadron® shell cuts wind and resists water, while adding warmth equivalent to 100 grams of down. Hadron® is a proprietary fabric we created to redefine the standard for superlight alpine durability.

It's made from a liquid crystal polymer ripstop fabric for strength that rivals fabrics twice its weight. The StormHood™ hood provides protection without compromising vision, and its gender-specific, articulated cut makes it comfortable over winter climbing gear.
