Millwall FC announced its continued association with CYC as main sponsor for 2009/10 season.
The distinctive CYC brand will again appear on the new home and away shirts and on all technical training kit.
The fast growing company will continue to have a major brand presence at The Den, as well as continuing their association as the club's official Logistics partner.
Ray James Millwall's head of commercial and marketing, commenting on the strength of the partnership with CYC, said: This is a fantastic agreement for the club in what is a very challenging market.
CYC has demonstrated a tremendous level of commitment to Millwall Football Club over and above the call of duty. Their renewed sponsorship will help us invest in the infrastructure of the club and build upon the success of the team over the past 12 months."
CYC Director Nicky Hayes added: "We're delighted to continue our association with Millwall in this way.
As a company we are developing and improving all the time, and over the past year Millwall have been doing the same.
I believe both the CYC brand and the football club have benefited greatly from this relationship and I'm confident we will continue to do so."
We are also pleased to confirm that Oppida will be continuing as our secondary shirt sponsor for the 2009/10 campaign.
