With the winter coming upon us (at least for those who live in the northern hemisphere, of course), you might want to take some precautions against feeling miserable by keeping yourself nice and warm. Our head is one place where major heat loss occurs, so wearing some sort of wool cap would help. If you want to stay nice and warm up there while offering a barrel of laughs to anyone and everyone who is nearby, how about the Undercap? This $16.95 apparel looks the same as wearing an underwear right over your head, where it is made out of 95% cotton and 5% spandex. Retailing for $11.95 a pop, we’re pretty sure whoever buys this won’t mind wearing it down there as well at least once out of curiosity.
