[2020] In the new update, the hazmat will now have durability.

As a point of reference:

• Wooden armour is 16
• Roadsign armour is 16
• Metal chest plate is 29

The downside to hazmat is that covers the full body thus would take more shots but it's still double the durability than anything within its tier.

Rustafied tests of 30 shots were done within 10m. Projectiles fired at distance deal less damage thus less conditional damage to the armour. In reality, the hazmat could sustain easily 40 or more hits in real-world PvP.
