Soooo, I bought these specifically for Halloween, as I went as a "BAD LAD ENTIRELY CLAD IN PLAID." I've always heard good things about Fahrenheit and wanted to find the ideal brief, ass I'm not a boxer dude. I also bought a green polka dot pair that I love (zero issues). The polka dot pair hugged my calves well, and I'm guessing, is the same "template," butt (lol) behaved differently.
The Tartan pair (awesome pattern BTW) did not keep its shape, as in, around my legs. I'm athletic and love quality briefs that hug my legs (no space/gaps developed) and these did, for about an hour...then, as if stretched out...the tartan became loose (around both my legs. I'm too lazy to return them, but am a bit bummed, no pun intended...or pun intended, ass there should always be comedy, even if sincerely disappointed in my tartan briefs. The polka-dot briefs, however, kept their shape (super nice) and I'm hoping this tartan was just the exception to the rule.
