This is an Operations Uniform from the recent Prop Store auction. The mock turtleneck and badge are replicas to complete the costume. The uniform consists of 3 pieces as follows:
Red tunic: made specifically for the sequel, the red tunics are made of Spandex, have piping around the collar and feature a printed optical repeat Starfleet insignia pattern. The long-sleeved shirts also have hidden zippers at the left shoulders. Pants: the grey twill pants were made specifically for the sequel and have ribbed fabric diagonally above the knees. Boots: also included are black leather boots with rubber soles. This is one of four Operations uniforms in the lot that I purchased from the Prop Store.
