a really simple solution, take a white latex glove (the thin ones doctors use) and cut the fingers off, the little fingers will fit the AA size fenixes, and the other fingers will fit bigger lights
its cheaper, easier to get, easier to replace and folds down smaller than this solution, although it looks a little funny pulling a glove finger over your flashlight
I would use both at the same time.
It seems very natural to throw a condom over that diffuser.:laughing:
After some trimming the diffuser sits snug in one end of the bezel protector and the other is snug on the bezels of my HDS and McLux.
