SINCE 2006 the Ospreys jersey has become a sales phenomenon, proving to be the second biggest selling club or regional rugby jersey in the UK and Ireland every season.
An independent report compiled in 2013 by Running Rugby, a respected website aimed at "decision makers in league and union", illustrated how the Ospreys continued to outsell their rivals, with sales running at double the number of the other three Welsh regions combined.
Yarnie Guthrie, Ospreys commercial manager, said he was excited abut the partnership with shirt supplier BLK.
"Our shirt is already a sales phenomenon and with the input of BLK and their fresh ideas we can build on what is already an incredible platform," he said.
"It's an exciting time for Ospreys Rugby, the start of a new era with a new kit provider, new commercial partners, new competitions and new players including a batch of young, talented Ospreys eager to play their part in the future of their region. Our supporters should share that excitement."
The South Wales Evening Post will once again feature on the region's jersey after reaffirming its support for the Ospreys as official media partner. The paper's logo will appear between the shoulders on the back of the shirt.
