Non-degrading Armor & Extra Armor Features v1.0 for S.TA.L.K.E.R. - Clear Sky v1.5.04 (European Version) - by Christian "CW"This mod should work with all versions of the game. It works without starting a new game and it works with old savegames. Every armor (normal and unique, correct me if I am wrong...) of the game is indestructible.
