Hydro-Fleece outer fabric reinforced with Cordura, Gore-Tex Supprescent laminated membrane with activated charcoal, and DuPont Thermolite insulation. Jacket, $440; bib, $280. All the bells and whistles: soft, warm, waterproof, versatile, and the scent control of Supprescent built right into the Gore-Tex membrane. On the whole, this stuff is very well put together.
