That's one thing I heard it called - there might be another name too.
Have you any idea if they'd be "fit for purpose" for the original poster and, I don't think I can put this delicately, is there an easy way for him to figure out what size he needs?
Haha - the things we discuss on this board - madness.
Frankly no.. they were fiddly things to put on someone else, but they are better fitted by the person who's using them. To get a "good" fit we used to trim any hairs short. use a skin prep soln to make the skin a bit more "adhesive" and apply. Proper fit was/is very important. They are prone to twisting and "blowback" which is descriptive and is exactly as it sounds.... Realistically they are best for static people in bed, with a "dribbling" problem, for active bushcrafters in a hammock, Erics' wide mouthed bottle is the way to go..
Possibly the most unusual reply to date I've made.: . but that the benefit of the forum...
