Materials: They are made with 2 mm thick neoprene, along with a highly elastic inner lining for a better fit.
Pattern: The extra-long pattern allows the gloves to overlap the wetsuit for better insulation.
I have Raynaud's syndrome (poor circulation in my extremities) and am swimming in ocean water between 47-49 degrees currently and these gloves are keeping me warm! Yeah to Orca for providing them!
