These briefs actually run kind of large which is why I usually seek them out. Ive never purchased the 10 pack before but I figured it wouldnt be any different than the smaller packs I'd bought before. I was wrong. These shrunk during washing/drying. I wash in cold water and dry on medium and have never had any of the Comfort Choice underwear shrink on me before but boy, these did. Maybe a whole size or size and a half. Im wearing them because I hate to throw them out and waste money but I dread it every time I pull one of these out of the drawer. Wont be buying the 10 pack again no matter how good the price. The material feels rougher than my others as well and just isn't pleasant to wear.
