Arc'teryx Fusion Pant Men's

Fully insulated, windproof and water resistant pant with excellent loft retention and good breathability. ThermaTek™ is an Arc'teryx exclusive insulation. The hydrophobic properties of this polyester textile make it quick drying and it retains warmth when exposed to cold/wet conditions. WINDSTOPPER® outer shell blocks wind entirely, sheds moisture and is a lightweight, easily compressible package. Full side zippers allow easy on and off over boots and gear. Excellent warmth to weight ratio.
