I know that some people are going to think this sounds hair-brained crazy, but trust me and try this. If you are consistent with this method I am going to tell you about, chances are you will never need to tape your blistered hands again.
Keep your razor in the shower and when your are about done showering and your skin is soft or pruney, run the razor over the callused spots. Yes - Shave off the thick skin that normally tears on your hands. Typically its the calluses from skiing or working out that will thicken up and cause skier blistered up or torn hands, especially when the water warms up.
Yes, you read it right... Shave off your calluses consistently and you will not likely need tape, neoprene power-pulls, or glove underwear any longer.
However, if you forget and do tear your hands open, use superglue if there is a flap of skin to glue back to your hands. It's basically the same ingredients that dentists use to substitute for bandaging and superglue stings far less than liquid bandage.
Good luck.
