REI Snow Ridge Mittens
Here's what other sites are saying:
The REI Snow Ridge waterproof mittens for kids keep young hands warm and protect them from wind and water. Flexible ripstop polyester shells allow full range of motion; reinforced tactile grip on palms and thumbs provides extra abrasion- and water-resistance. Aquabloc(R) inserts are waterproof and windproof, yet breathe well to keep small hands warm and dry. Polyester insulation adds warmth without a lot of bulkiness. Polyester microfleece linings wick moisture away from hands so they don't get clammy during high-energy fun in the snow. Soft fabric on the thumb gives you a gentle place to wipe your cold nose. Adjustable nylon wrist straps secure the fit. Stretchy fleece cuffs seal out snow and cold while trapping heat inside.
