I cup it/palm it too. This will make me smell like smoke so much more than if I kept my hand away. This could be bad if you have to step into an office or client meeting after smoking. When working from home this is my method of choice.I smoke outside only. Any pipe will work. If it's truly miserable, do you really want to be out there? Occasionally wind, rain and so on, just put your hand to cup the top. Don't completely cover it.
What king of pipe is best for smoking outdoors I a windy climate?
