They are quite funny looking. Those are 3 finger 7mm scuba gloves. You can use these gloves for extreme cold diving (below 32 degrees) to prevent ’White Fingers’. When the hands get too cold, the blood flow is restricted. Keeping fingers together is one way to fight it off. Still, you have to limit exposure to about 30 minutes. The water this day was about 30 degrees. Yikes!
