Black Diamond Spark Mitts vs Burton Toddlers Grommitt

They were not too tight as to get cold and they were not too sloppy as to feel limited in mobility/ dexterity. On a cold day at the resort (15degrees F), my hands did get surprisingly cold for having mittens. But now i know the lower limit of the mitts and know not to wear them in cold weather. For fair weather, they are the perfect mitt though

We've had size 1, 2, and now we just bought size 3. They seem to run a bit small. They come with an extra removable foot bed insert that is supposed to give you room to grow but the size 3 boot with the room to grow insert fits more like a 2 1/2 with the liner in and a 3 without the insert.
