This is the new Liverpool Air Max jersey 2021, a special edition shirt released by Nike as part of their Air Max collection. It’s unofficially said to be the club’s fourth kit, but the Reds will not wear this uniform in any competitive game during the 20/21 season.
The new LFC Air Max top features a pinstripe design which extends to the reverse, as can be seen in the pics below. Skipper Jordan Henderson is here seen modelling LFC’s new 2021 fourth kit.
