The Mitten WB is a wind and water-repellent overmitten, thanks to the membrane laminated onto the fabric. The palm is 100% goatskin, and the back is a strong, supple fabric in 100% polyester. Elastic around the wrist base for a good fit. The long wrist section can be tightened using a drawcord. Removable wrist strap for fast putting on and taking off. Available in white and brown.
