Outside heat from direct & reflected sunlight is kept out by using a reflective outer layer, backed up by layers of insulation. When you look at the flimsy-looking outer covers of the Lunar Module, you're only seeing the reflective skin that covers the actual structural members and pressure vessels beneath. Interestingly, Middle Eastern nomads developed the same principle centuries ago: Those volumous white robes they wear serve the same function, and work better than shorts and a t-shirt to keep them cool in the desert.
