It's not as easy as it sounds to make waterproof mittens for kids. We not only wanted to "end the thumb wars" with our Mittyz but make a warm, waterproof mitten as well. Just about every major accessories manufacturer claims they have a "waterproof" option but in our extensive testing and market research (and just being a parents!) we knew this just wasn't always the case. It' pretty easy to tell when your child has wet hands especially when the inside of their gloves are soaked.
So how do you make a waterproof mitten? Lots and lots of testing, excellent manufacturing techniques, and superior fabric choices. We tested dozens of our first production samples, in the snow and on children, we held them under faucets, we filled them full of water. Guess what? Some of them were not keeping water out! Through our testing we found that occasionally through a sewing error the waterproof/breathable membrane would be pierced by a sewing needle and just like that...not so waterproof. We had to go back to the drawing board and come up with a better way to manufacture a children's glove, do it in a way that nobody else was. So that's what we did. The technique's we use to achieve this are expensive and found in only the highest levels of manufacturing, something most brands just aren't willing to do "just for a kids glove", but we are on a mission to bring you and your kids the best mitten possible.
