We use our proprietary four-layer fire protection system developed by the Wild Things product development team to insure full protection from flash fire AND protection from cold, wet weather in a cost effective product. The Smoking Jacket��� is designed to function, wear, and pack as a lightweight insulated jacket. A water-resistant shell combined with minimal seaming keeps wind and water out. The Smoking Jacket��� features an innovative neck seal engineered to keep flames away from skin and base layers while acting as a typical high protective collar. FR protection extends to every detail of the Smoking Jacket���.
