ELI5: How are astronaut suits built in such way so that there are absolute no gaps or holes for air to escape? What is the material provided?

We are good at making stuff with no holes. You can buy a drysuit for a couple of hundred currency units and can be pretty confident it will have no holes.

Also atmospheric pressure isn’t very high, a diver going to 100 metres depth needs a suit that is airtight to 10 times the pressure a spacesuit needs to withstand.
