There was a poster on here who used to do some professional looking mock ups on here, but can't remember his name. Possibly one of his.
When I first saw the image something didn't look quite right, but I couldn't put my finger on.
And I got that shirt LOL
I think theres definitely going to be a 3rd kit.
The site I saw the away launched on said:
"Rotherham United revealed the first of two ‘secondary’ kits manufactured by Puma Teamwear which will be worn by the first team on their travels during the 2020/21 Sky Bet Championship campaign"
