Wild Basin features the Eureka "Therma Shield" insulation. Therma Shield is a proprietary 7 hole polyester fiber fill. Each Therma Shield strand contains 7 hollow tunnels that run the length of the strand. These tunnels create dead air space that effectively retains body warmth.
Constructed of a polyester mini rip-stop outer shell with taffeta inner liner. Double layer off-set multi-needle quilt construction helps prevent cold spots by eliminating thin areas in the insulation. Fully adjustable contoured hood and adjustable storm collar. #5 non locking, self repairing zippers.
