Last week we gave you a sneak-peak at the Mac Miller x Mountain Dew x Diamond Supply Co. collaborative snapback hat. Limited to only 100 online pieces, the hat literally sold out within a matter of minutes. Chances are you didn't get a chance to buy one, but you can still grab one if you're lucky.
KarmaLoop is holding currently holding a contest, with the prizes being that hat and various other free stuff. You can enter that contest right here.
