The tough, feature packed Brush-Tuff Extreme ATS (Advanced Tracking System) hunting waders provide the ultimate in waterproof protection.  Heavyweight 5mm fleece lined neoprene with abrasion-resistant bidirectional facing protects against punctures.  1600 gm Thinsualte Ultra insulation in the boot keeps the feet warm in the coldest water.  An aggressive ATS outsole system, attached shell holder, headwearing double-stitched seams and reinforced knees help make these waders a must have for cold wading conditions.
