Rust Armor Simulator

Pick a kit, set how many insert slots each crafted piece rolled, then try different inserts.

Armor inserts

Protection by body area

Each body-area cell adds up the base protection of every piece covering that area, plus that piece's inserts, capped at 100%. Kit total adds every worn piece and insert once, uncapped. Rust's in-game summary may combine these differently, so compare one kit against the game before relying on it.
