I'm not one to write reviews, but at the same time, I rely on them when making purchases. I had a difficult time finding winter GLOVES for my very active 2 year old until I located these. (If I remember correctly) - my son has 15cm circumference palm and 17cm circumference hand (measure around palm including around the thumb) and Scheels replied quickly & accurately to my email to order size XS! The fingers were a little long, but the glove fit in his hand! A few cons: I wish the glove somehow opened more (velcro or something) to assist with toddler's finger placement and I wish it had a longer cuff to prevent wind/snow. Overall, I would recommend these gloves!
