The minimalist Warmbib spreads heat across the chest. It's made with a Gore-Tex Windstopper outer layer and comfy microfleece on the inside, with the heating layer sandwiched between. The low-profile fleece collar closes with hook-and-loop. The bib self-stores in a built-in zippered pocket. A fused, lighted power switch/coil cord is included. The Warmbib has two fits all sizes, regular and tall, and is priced at a modest $97.
