Travel John (pack of three)
Absorbent pouch turns urine into gel instantly while destroying bacteria
and odor. Specially designed collar works for men, women and children;
spill guard prevents back flow during use. Convenient, sanitary and
compact, the Travel John is easy to use while sitting or standing. Will
not leak, even if punctured. Keep several in the plane, car or boat.

What I want to know is how easy it is to unzip and fish out one's
personal apparatus through briefs and a jeans fly and poke it into the
pee-pouch while flying a C150 solo (nobody to fly the plane while you
struggle with the business).
