Last July I was in Dumbarton where I purchased the kilt in my profile pic (The picture was taken outside Overtoun House). I did not take a sporran and decided not to purchase one. It was in the 70's and I was actually cool bordering on down right cold at times. Perhaps with the lack of a sporran I wasn't as warm as I'm sure you were, but I know this, shorts can't hold a candle to a kilt in comfort.
