I've been searching for 2hrs now and can't find the post that mentioned underwear that is seamed like bike shorts. All the search results are from UN yelling at people for wearing underwear under bikeshorts.
I'm in the market for new guchhies so I was going to give them a try. Oh yeah for Guys....
Some bikes. Hell, they're all the same, ain't they?
"guchhies"? "UN yelling"?
Anyway, I haven't yet seen underwear that is truly seamed like bike shorts; their panels almost always meet at the 'taint, right where you'd sit on them on a bike saddle. I have some spandex boxer briefs that used to be sold at Target that are about as seamless as you'll find, and Under Armour briefs are pretty close.
I'll keep watching this thread myself for some better options.
