Its actually relatively simple. There are really two basic conditions a space suit must provide: temperature and pressure. The moon is in a vacuum. A vacuum is a vacuum. They are all pretty much the same. Next is temperature - even without a probe on the moon, you can read temperature simply by looking at it in infrared: the color of the light is determined by temperature.

Now there are, of course, other issues: sunlight (face shield), mobility, communications, etc., but none of those issues are specific to being on the moon.
