The Hunting Wear made by Carrabassett Polar Wear has several superior qualities.
Quiet - The blaze orange fleece is soft and does not make noise
Warmth - Fleece is the ultimate protection against the cold and does not steal body heat if wet.
Dries Quickly - Fleece dries quicker than almost any other fabric
Fleece, huh? Cheap, acrylic fleece. Like a blanket. Long, soft fibers. The kind that could get stuck in a lacy plastic necklace while one was carrying a body.
