Trick Little Portable Heat Pad
Went to a scuba diving trade show and one booth was selling these neat little heating pads. I guess you’re supposed to drop them inside your wetsuit, but I immediately thought of PE uses :chuckle: It’s a sealed bag of basically salt in a liquid state that when a “clicker” is pushed starts a reaction that crystalizes the salt and produces 130 degrees of heat. Smaller sizes last about an hour and the larger sizes about two. They are reuseable. The only drawback I see to using one all the time is to get them back to the liquid state you have to place them in boiling water for 6 minutes, but that might be better than standing in front of a microwave waiting for a rice sock to heat up.
