add a lightweight model of the diving suit, from the original it will differ in that it will move faster and it will look different. If the player enters the pressure zone, the inscription appears (you have entered the danger zone immediately leave it) and the timer will appear disable protection.

There's a similar thing to that in BTE. It's a wetsuit and diving mask.

Maybe the suits could be assembled in different parts when your crafting them and if your cheap you could only use a few parts but it would only protect you so long or the oxygen will drain faster
