The club issued a statement revealing that, following an “extensive tender process,” Hummel were chosen from more than ten hopefuls.
The partnership had been heavily rumoured on social media earlier this week.
The Aarhus-based firm, which currently produces strips for the Denmark national team, Brondby, Charlton Athletic, Strasbourg, Real Valladolid and Clyde among others, will produce three bespoke kits for each season, along with a number of training gear products.
Rangers Managing Director Stewart Robertson said: “We are delighted to announce that our new kit supplier from next season will be Hummel and we are sure the fans will love the design of the new shirts featuring the famous Hummel chevrons for the first time.
“We would also like to place on record our thanks to Puma for their support over the last few years.”
Hummel CEO Allan Vad Nielsen added: “We are extremely proud to have been chosen as the new Technical Partner to one of the world’s oldest and most famous football clubs.
“Words can barely describe the level of excitement at our Head Office this morning when we announced this fantastic new partnership to our International staff.”
“At Hummel we pride ourselves in doing things a little differently by adding that extra twist and a bit of character to all that we do.
“Over the next 3 years we will endeavour to provide the players, staff and most importantly the supporters of this great club with an exceptional range of products both on and off the field and we look forward to joining you on your journey back to the top of the league.”
The new kit will be worn for the first time during Rangers’ pre-season fixtures in the summer.
Hummel has previously sponsored Hearts and St Mirren in Scotland, and currently makes kits for Newtonmore and Skye shinty teams.
