I have a pair of these I have had for years, now I need them since I have got older, but think I lost the mittens that can go inside these. However the best part is you can take the thumb and first finger and they have a slit your thumb or finger can go through and the tip of the finger/thumb with fold back and stick to some velcro to hold your finger and thumb free.
