Our Mittz (both Infant and Youth sizes) are lined with 3M™ Thinsulate™ (150 grams per square meter of insulation), making them one of the warmest children’s mittens on the market. This form of insulation offers superior warmth, is soft and breathable so your little one remains comfortable, and it is highly durable.
The outer is made up of wind resistant coated 600D Nylon shell which is used to keep wind and snow out of the Mittz. They are now also 100% waterproof!
Our Mittz have gained massive popularity among customers in Russia, Norway, and northern Canada and that's why we can vouch that our Mittz keep hands warm in extreme Winter conditions!
