Transfix incontinence condoms. Roll on, attach to pee tube (either routed to outside the glider or to a suitable bag), and no hassle, no chance of leaks.
Tried that. Once. The damn things glue to you and don't let go easily.
The same shops sell water-absorbing crystals -a teaspoonful in a plastic bag (or one bag inside another, just in case of leaks) works really well, though some practice in finding the best position is recommended.
Only for male pilots though, because of the seating position as already explained.
