A Sporran (Scottish Gaelic for purse), is a pouch that is worn with a Kilt. It takes the place of pockets because a Kilt doesn't have pockets.
Sporrans also prevent the kilt blowing upward.
The sporran is a pouch that performs the same function as pockets on the pocket-less Kilt. Made of leather or fur, the ornamentation of the sporran is chosen to complement the formality of dress worn with it.
