"These gloves keep our hands warm and comfy! They easily fit over the sleeve of my jacket, even though it has a zipper and snap at the cuff. There are two points of straps you can use to secure it if you like. Dexterity is good, an improvement over my previous non-heated gloves. The batteries last as long as promised and are easy to charge w/o taking them out of the glove. The only suggestion is to adjust the size charts. According to my palm size, I take a small but I found a medium fit me best. So if you are right on the cusp of a size, I recommend going up one size."
