All Stonz Mitts are lined with 3M™ Thinsulate™ (150 grams per square meter of insulation), making them some 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 is highly durable.
The outer is made up of wind-resistant coated 400D nylon shell which is used to keep wind and snow out of the Mitts. All of our Mitts are also 100% waterproof!
Our Mitts have gained massive popularity among customers in Russia, Norway, and northern Canada and that's why we are able to vouch that our Mitts keep hands warm even in extreme Winter conditions!
