Rangers have described their new deal with Castore as "one of the most valuable commercial partnerships in the club’s recent history" after agreeing a minimum five-year contract.
It was confirmed on Sunday morning that the Liverpool-based sports brand will supply the Ibrox club's kits and merchandise for the 2020-21 season.
And that connection to Steven Gerrard 's home city convinced the Gers boss that the new partnership will be a perfect fit.
Gerrard said: "This is a significant moment for our football club. The Beahon brothers, like myself, are proud of our Liverpudlian roots.
" Liverpool and Glasgow are proud cities. In both cities, the city makes the football club, and the football club makes the city.
"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."
The new agreement comes after Rangers broke off a deal with Hummel one year early following a court battle with Mike Ashley.
And the Castore contract has been described as one of the most lucrative in recent years.
A statement said: "The multi-year partnership stands as one of the most valuable commercial partnerships in the club’s recent history and represents a major milestone in our ambition to achieve excellence, at every level of the club, in anticipation of our 150th anniversary year.
"Castore have deliberately selected Rangers, the world’s most successful football club, as their flagship club, as they enter the football market, which will see them partner with 3-5 other major clubs across Europe in the next 18 months.
"Castore is backed by a consortium of high-profile private investors worth a combined £5 billion. They include one of the UK’s wealthiest families who have invested to facilitate Castore’s entry into the global football market, where the brand believes there is an opportunity to disrupt the established players at the highest levels of the sport.
"The company operates a digital, direct-to-consumer business model that has allowed it to grow extremely rapidly since launch and avoid the much-publicised challenges of many traditional bricks and mortar brands and now sells into 64 countries globally."
Castore will also take over the retail aspect of Rangers' operations, which will see the Ibrox Megastore selling the new kits.
The store was previously managed by Sports Direct under the terms of a previous agreement with Ashley.
Rangers interim vice-chairman John Bennett said: "Kit and merchandise has been one of the great challenges faced by Rangers and its loyal supporters in recent years, and this wonderful new partnership with Castore offers us a new beginning. This is a clean slate. A fresh start. A new era.
"We recognised instantly that Castore are incredibly ambitious but also have a strong financial backing through their shareholders to support this ambition.
"To be able to offer the products of our outstanding new partner at our Ibrox home is very significant. We can’t wait to see our supporters once again going through the megastore doors."
