Here’s another piddle pack--

In reading through the contents of Brent Blue’s Emergency Medical Kit (
http://www.aeromedix.com/aeromedix/art/medkit ) he lists:
Urine/puke bag—The #1 TravelJohn is the best of the products we have tested. The internal polymer absorbent material gels any liquid, making it spill-proof, and neutralizes odor. These cannot be used for water storage or transport because it cannot be recovered from the gel. Can be used for ice or cool packs when placed in a freezer or filled with cold water. … The mouth of the #1TJ bag is a semi-rigid "unisex adapter" shaped to make the device suitable for use by females as well as males.
