The inner wrist area is a bit loose. I don't think it'll be noticeable when you wear it, but... If you're okay with that, m(_ _)m, and understand, please consider. Perfect for this time of year! Handmade hand warmers. Hope they help keep you warm ＼(^o^)／ Since the inside is open, it shouldn't affect your swing, etc. Inside... Fleece material Outside... Knit material Wrist... Knit material My hand size is about 16cm, measured from the middle finger. They're sewn securely, so I don't think they'll unravel easily... These are handmade, so please refrain from purchasing if you are looking for perfection.
