Winter is here and so, thankfully, are long johns (and pictures of barefoot guys in long johns). Men's underwear brands went headfirst into the oft-ignored cut of underwear this winter to allow their dedicated customers the chance to wear their underwear year-round.

Everyday brands as varied as Andrew Christian and Emporio Armani have released supersleek, ultra-comfortable long underwear and luxury brands like Hanro and Under are getting in on the game, too.

Sparked by Nasty Pig, a new trend has even emerged: Long johns as outerwear.

Check out our collection of long johns from brands you may never have heard of as well as looks from brands you probably didn't previously associate with winterwear.
