How about bringing enough so you can wear a clean pair each day? Mine are small enough to stash in my suitcase. and I only travel with a carry-on suitcase.

Even though I've giggled at this post, I was reluctant to add to it. But here goes; for Xmas I bought my hubby a few pairs of Jockey micro fiber boxer/briefs and he loves them. Apparently, they are very comfy as they have a pouch that poofs out enough so everything fits. Plus his pants are definitely "perky" and they dry in a very short time. We tried it on a damp day.
A word of warning though, it's a tricky business to buy men underwear. It's almost as thorny as buying a purse for a woman.

Ah, but Wanda wanted her man to look perky in his pants, it would be a strain for alot of men to do this w/o briefs.

I have to admit that I have noticed perkier pants on adult Euro men and our poor young men in the US are wearing those horrible baggy droopy pants on purpose, no sex appeal IMHO.

thank god this discussion has petered out.....

uuhhhh, you're SO BAAAAAD!

I hate to insert a serious note in this thread but had to give our solution to this "problem". We save our old nearly worn out underwear, socks, pj's for travel....wear and then discard....no washing, leaves room in luggage for souvenirs, etc.

Ok, as long as we are still on the subject, let me add the old balloon trick...

Along with those cotton or nylon or silk or woolen briefs, pack a dozen kids round party balloons. Come wash day,simply inflate and dress your damp drawers in the balloon. Attach attractively attired balloon to nearest rack, doorknob or hook to dry. Works fast and marks you as a real party animal for curious housekeeping staff.

And if you don't have balloons, condoms can work as well. If you think the balloons made the staff think you were a party animal. . .

I don't have room in my 22" carryon for all those old undies, let alone a dozen kids! How do you all do it?

I was in Utah recently on business and they were telling me about this special underwear that some people wear as a religious thing. They are basically long johns, but with a slit in the back so you don't have to take them off to poop. I didn't believe them until I went to a Halloween party months later and someone was wearing them! Too funny...I approached him and told him my story and we had a good laugh.
