What do ISS spacesuits do? I know they provide an at atmosphere but do they have insulation? I’d guess not because there’s no atmosphere to cool you down, but what about depressurization?

A spacesuit is like a mini , personal space station. I’m not sure why you think a spacesuit doesn’t need insulation. It absolutely *has* to have insulation. Otherwise, you’d bake to death when facing the sun and freeze when in the shadow of the Earth. We’re talking about hundreds of degrees above and below zero. Heat is actually more of a concern than cold, so the astronauts wear a garment that has tubes sewn into it. Cold water flows through these tubes and keeps the astronauts from overheating. So in addition to the pressure bladder that contains the air, yes, there are many layers of insulation as well as layers of kevlar or similar material to protect against micrometeroids.
