A navy seal would NEVER fit into that skinny as hell suit.

No it won't. It's only strong in one direction, like nanotubes. You can pull it as hard as you like, but it's shit against compressive forces.

A good exo suit would need a seriously lanky person inside so that they would actually be able to move normally once you fatten them up. There is a real limitation when you have to use the existing joints of a human body as the rotation points while adding material around them. Like wearing thick gloves but worse.

>It's not instantaneous,
The problem is the impact even of the bullet is NEAR instantaneous, so maybe your nanomachines son armor repairs the damage, but not until the bullet has already done its damage to you.

We have discovered these materials and you use these materials everyday. It's just you don't use them to space colony or to kill aliens, so you don't care.
