For a successful hunt an effective layering system must work. These Mack's Prairie Wings Layering Fleece turtleneck shirts all offer super soft next to the skin comfort and are extremely quiet. Made of 280 gram polyester fleece they wick and dry quickly. All shirts are cut full and the two-way stretch provides freedom of movement. To simply say that these shirts are warm doesn’t give them justice. The natural warmth trapping ability of fleece makes these shirts the ideal choice of staving off winter chill.
