Castore has been unveiled as Rangers’ official new kit and retail partner.
The sportswear brand has agreed a minimum five-year deal from the 2020-21 season.
The Glasgow football club have signed the new contract after breaking away from Hummel early following a legal battle with Mike Ashley and Sports Direct.
Castore – founded by Tom and Phil Beahon – operates a digital, direct-to-consumer business model and is backed by a consortium of private investors.
Rangers manager Steven Gerrard said: “This is a significant moment for our football club. The Beahon brothers, like myself, are proud of our Liverpudlian roots.
“These guys understand the level of expectation on the clubs in our cities, that goes beyond simply winning football matches.
“This is a way of life. It is about setting the standard in every single facet of our club. It is about bringing everyone wearing that badge together. Castore get it.’’
Stewart Robertson, the Ibrox club’s managing director, said the team were “thrilled” with the “terrific new partnership”.
Castore’s Tom Beahon said: “In our search for our first elite club, nobody came close to matching Rangers.
“Our business has grown rapidly since we started and we now have a group of very strong investors backing us, with very high expectations.
“Partnering with Rangers is a seminal milestone for us on our journey of building Castore into the brand we want it to be and we have absolutely no intention of stopping in our pursuit of our goals.’’
Phil Beahon added: “We have built this business ourselves, from the ground up, brick by brick. It has taken sacrifice, pain, and an immense amount of hard work to get us here.
“Rangers supporters are in every corner of the United Kingdom and beyond. We are excited about seeing our brand, in royal blue, spread across the globe.”
