The Patagonia DAS Parka provides us with uncompromising protection in intense conditions, from bone-chilling belays to cold nights camping in fire-free zones. Its hardwearing Pertex fabric defends against all manner of wind, weather, and rough surfaces, while synthetic insulation ensures toasty warmth no matter the current conditions. The PrimaLoft Gold insulation is fused with aerogel technology to offer exceptional warmth and softness, and Patagonia gave key areas an additional 40 grams to further lock in comfort.
