A leaked video clip has surfaced online that appears to show the new Rangers away kit for 2021-22.
Castore look to be ramping up preparations for a third season as the club's kit suppliers.
The Liverpool designers were a surprise choice to take over as the club's official kit supplier after a deal with Hummel was cut short.
Despite an initial warm reception some of the offerings have been criticised.
A recent misstep from the kit brand saw some fans who ordered the legends top, which would be worn against a World XI during the Ibrox 150th anniversary celebrations, sent a mystery blue kit.
Some fans believe that they received next season's new home kit in a mix-up.
In the latest issue for Castore, the new Rangers away, or third kit, for the 2022-23 season appears to have been leaked online.
A clip showing John Lundstram involved a photo shoot in a a full black strip has offered a major clue to one of next season's choices.
The kit is all black with blue trim on the collar. The Rangers badge is also blue, while the sorts have two blue stripes down the sides. The socks also have a blue Rangers crest on the shin.
No official announcement has been made on the new kit as of yet with Gio van Bronckhorst 's side battling in the Scottish Premiership, Europa League and Scottish Cup.
