I have a gift card for SW and I am hoping to upgrade some of my cold weather hunting gear. Right now I use insulated carhartt overalls. They are heavy, and soak up water like a sponge, they are not ideal for what I do. I sit on snow, ice, and bare ground quite often so I am hoping for overalls that are waterproof, insulated, and lighter in weight than Carhartts. Any suggestions?
