For a successful hunt, an effect layering system must work. Mack's Prairie Wings Fleece Turtleneck offers super soft next to the skin comfort and is extremely quiet. All Shirts are full cut and feature two-way stretch which provides freedom of movement. Made of polyester fleece, they wick and dry quickly. The natural warmth trapping ability of fleece makes these shirts the ideal choice for shaving off winter chill. To simply say that these shirts are warm doesn't give them justice.
