The Hail Call Waders by Lacrosse were designed to give waterfowl hunters the adaptability they need in their field. They feature 1600G of Thinsulate insulation, and 60G of quilted insulation in the upper half to keep heat trapped inside, and should more warmth be needed, the interior is spacious enough to allow multiple layers to be worn underneath. Should the weather be warmer, these chest waders can be quickly converted to pant waders to help the wearer cool off. In addition, the Hail Call waders feature a pouch and hand warmer in the chest to keep your essentials close and your shooting hand warm.
