Whether you're glassing late season goats, layering for a long sit in the stand or sitting around a chilled, backcountry camp, the Uncompahgre Puffy Pant provides the hunter with packable insulation for the lower body. At a mere 18 oz., this highly compressible layer features a very toasty 100 gram, 37.5 synthetic insulation. Full side zippers and Velcro waist clasps mean you can get this pant on or off in seconds without taking off your boots while allowing you to layer them over your pants if desired. An exterior DWR and reinforced seat resist moisture and tears while on the move or sitting pat. These features make the Uncompahgre Pant an excellent choice for the hunter who demands serious warmth from packable insulation.
