After talking to a few friends and my son last night, we have a new plan to try. Depending on weather and elements we will use Nitrile gloves, wool fingerless gloves,and adult medium striker mittens clipped to his jacket. The idea is the nitrile and wool can keep his hands dry, provide some warmth, and allow for dexterity. The mittens clipped (yes, old school strecthy clips) to his heavy coat will hopefully allow for these gloves to stay dry and not get lost. These would be used for when we are walking out, getting things ready to go or put away, and to help warm up hands throughout the day, with the ability to put in a handwarmer for additional heat, and the large size lets these come on and off fairly easily. Best part was we had all three of these pieces of gear on hand. We'll see, but it seems like a decent idea.
