Toddler (2-4) Girls Embroidered Velcro Closure Mittens (Thinsulate Lined) HOW DO THESE BOYS / GIRLS TODDLER / INFANT WINTER MITTENS FIT? These ski mittens fit true to size for ages 2T  4T, but are not limited to this age group. The interior mitten area measures 6 long x 3 wide (seam to seam). This amount of room transforms the mitten into a snow glove for kids, baby girls and boys, and for older boys whose hands still fit within the 3 w x 6 l area. THINSULATE TEMPERATURE RATING: These toddler mittens come with 40 gram Thinsulate lining and are best for temperatures of 20 degrees Fahrenheit and up, making them the perfect weight for most regions in the United States with exception to those in extreme cold. Baby mittens for girls or boys with 40 gram Thinsulate are thin enough to allow for great flexibility yet arent too hot  heavier weight Thinsulate is extremely warm and can lead to sweaty hands which isnt ideal in cold weather ARE THESE KIDS MITTENS WATERPROOF? The quick answer is yes, but the more accurate answer is yes, these winter mittens are waterproof under NORMAL use conditions. Normal use conditions include playing in the snow, sledding, going to the store, all standard outdoor activities in the cold and snow. Feel good sending your child outside and expect your kids hands to be warm and dry under these situations. HOW DO YOU WASH / CARE FOR THESE WATEPROOF MITTENS? While hand washing is ideal, its not always practical. These baby mittens can go in the wash machine on delicate and be partially dried on delicate. We recommend NOT drying them fully and allow them to partially air dry. The exterior shell, liner, and filling are 100% polyester, and the Thinsulate is 65% Olefin/35% Polyester, but there is a synthetic waterproof shield between the shell and liner that could be compromised by extreme heat. WHAT OTHER FEATURES DO THESE MITTENS HAVE? These mittens come with a Velcro wrist strap and elastic band that allows you to expand the opening of the mitten to make it easier to get them on and off, while also keeping your childs hands warm and dry. Rubber Tech grip can be found on the palm allowing for a sturdier construction and a better grip when handling items. The exterior of the gloves features a hook / slot function to connect the two gloves and keep them together.
