Suggestion that has worked for me. Careful not to cut off your circulation!
1. Put a Rubber (Latex glove) on your hand.
2. Shave any arm hair at the wrist and duct tape glove securely to wrist.
3. Place a double (O-ring seal) over the duct tape using two snug (but not constricting rubberbands.
4. Place your hand inside a "dry glove" (one with a wrist seal) that is snug on top of your duct tape and rubber bands.
I've done this a few times and my hand has stayed completely dry (other than some sweat : )
