Lionhill said:The ones I have are actually sold as flyfishing gloves, and though not evident in the photo, the thumb is can be exposed. Mine have been submerged in a stream and were dry 20 minutes later. You need to get the type of material like polar fleece or equivalent fabric that suits the purpose and the temp rating. These ones have no blood flow restriction in my experience.
This is a better image that shows the neoprene hands, and the thumb opening.
