i thought about the hem of the shorts too. i've turned them over so the sticky stuff is away from my skin. no apparent effect.
i haven't seen the article on the different sun screens. my dermatologist, without doing patch tests or something like that, thought it best that i stay away from screens that are more chemical and stay with the mineral based ones. that's why i stay with the titanium or zinc, opaque covers.
my knickers are due here monday or tuesday. and the long term forecast is for high 80's and humid for next saturday when i have a century. so it will be a test right away. i guess the leg coolers will be the next option. fortunately not as expensive as the knickers. either that works will be a good investment. thanks, fran.
