These pogies use the same technical waterproof fabric as high performance ski and snowboard jackets. The outer layer is 100% waterproof, they have an insulation layer and a technical fleece lining for complete warmth while biking. No need to use your gloves!
The outer layer material are all scraps that were either too small for industrial purposes or were left-overs from outdoor gear manufacturing. The fleece layer is made from unwanted material from a large outdoor apparel manufacturer. All pogies fit on both drop and flat handlebars.
(Note: they don't currently work on Shimano STI shifters).
