Its cold up there on the Moon. At least that is what those who ventured far tell us. That is, if they actually have been there...\n\nHere on earth it is less cold, so you don't need a full astronout suit but a jumper will do. Or a sweater if you prefer one of those. \nAnd on not too warm days, a pullover can also come in handy. \n\nCall him however you want: Neil is that piece of clothing that jumps out there.
Note: in doubt about size? Take the larger of the two :)
