This is a Stunt Riddick costume (with David in the tags) from The Chronicles of Riddick. Unfortunately both the gauntlets and boots have been seperated from this costume at some point and I have so far been unable to track them down. Pictured here with a set of gauntlets I made as a test-piece using a pattern taken from one of my screen used sets and a pair of old army boots.
