The jersey, inspired by the famous club badge, has a yellow and black threads worked through the traditional red base.
Men's stars Marcus Rashford, Aaron Wan-Bissaka and Daniel James joined members of Manchester Untied Women Jessica Sigsworth and Katie Zelem to model the fresh new look.
The top is created using Adidas's HEAT.RDY cooling technology, while white shorts and black socks complete the look which Ole Gunnar Solskjaer's men will wear upon their return to Champions League competition next season.
Adidas design director Inigo Turner said: "[The crest] is the representation of the heart and passion of the club, it is symbolic and iconic across the world.
"It is significant as the first component added to each design, and one that makes up the threads of the shirt design for the 2020-21 season.”
The players will debut the kit on Wednesday night as United resume their 2019-20 Uefa Europa League campaign at home to LASK.
The new shirt is available to buy exclusively at adidas.com/football, adidas stores, and official club stores. Wider release from August 11.
