Cold & Wet Alpine Conditions.

The versatile and understatedly durable women’s THORIUM AR Hoody is an alpine specialist, wearing perfectly as a warm mid-layer in cold backcountry conditions. Its core and sleeves are padded with plush yet resilient 750 fill European grey goose down, delivering incredible lightweight warmth and packability. Down Composite Mapping combines the down-fill with panels of hydrophobic Coreloft synthetic fill. This synthetic insulation is placed through the hood, collar, cuffs, and underarms, which are areas prone to moisture. Abrasion resistant and textured Arato 30 outer fabric treated with a DWR finish sheds the wind and light precip. The entire StormHood is lined with Coreloft fill, preventing soakage in sleety weather. Concealed hand pockets close with zippers, securing your phone, map, or music device. This insulators' regular fit, contoured to the female shape, easily layers under your hardshell.
