This is our word for the windproof design we apply to our vests and hoodies. The Hoodie has velcro cuffs on the sleeves, elastic bungee cord on the waist, and elastic bungee cord on the hood. The Vest has the same technology on the waist, plus a storm flap behind the zip, elastic arm holes for a snug fit, and a double-thick collar to block the wind on your neck. With BÆRSkin there's just no way for the wind to get in.
