Brace for incoming weather with waterproof performance and dependable warmth, it's the perfect mitten to ride out any winter squall. GORE-TEX technology keeps water out of these Gordini mitts while allowing moisture from the inside (perspiration) to easily escape. The result is a highly breathable, totally waterproof snow mitten. Synthetic insulation and moisture-wicking lining keep hands warm and comfortable. If you want to attach your own mitten leashes, there are leash attachments. Gauntlet cuffs with drawcord closures and wrist straps fit over jacket sleeves. These mittens should fit snug but not tight. If you are between sizes, size up for maximum comfort. To determine your glove size, measure in inches both your hand circumference (flat, from crook of thumb around outer edge of palm) and hand length (fingertip to the bottom of the palm). Men's sizes: S (circumference 7.5”-8” and length 7.5”), M (circumference 8.5” and length 7.75”), L (circumference 9”-9.5” and length 8”), XL (circumference 10”-10.5” and length 8.5”), XXL (circumference 11”-12” and length 9”). Spot clean and air dry.
