I've been diving with hair on my upper lip for more than 20 years. I find that the vaseline trick is less effective than 1) a well fitted mask and 2) trimming under my nose - in that order. How far down to trim depends on the mask fit. Have him look in the mirror with the mask on an judge it from there. (you're not allowed to laugh at him:D ) I would suggest he start the trim habit a couple of weeks or more before you go. Its amazing how tender that skin is when it hasn't been shaved for a while and a shaving rash under a mask skirt hurts!

Before you buy take a look at these folks http://www.hotshirts.com/ company name is Paradise on a Hanger Really high quality cloths and good customer service. Getting good multifiliment rayon can make all the difference in comfort!

I have an international size roll aboard. Use it all the time. Its not all that lightweight though, about average.
