"Things change," said Davies, who toured with the Lions as a Test wing in 1971 and will now take on a managerial role alongside former team-mate Ian McGeechan and his coaching staff.
"This is the fourth time that adidas have sponsored the shirt and, during that time, the design has changed. It's become more dynamic, more aerodynamic and other scientific words you'd like to use!
"Adidas have changed the design, but the meaning stays the same. It's still the Lions badge on the breast, and that is very, very important."
The Lions first wore the adidas logo on their most-recent tour to South Africa back in 1997 and the company have since produced the kit for the 2001 and 2005 tours of Australia and New Zealand respectively.
The new shirt for 2009 has been designed to aid all aspects of performance against the world champion Springboks and is 30 percent lighter than the previous model worn against the All Blacks.

For Davies, the launch of the new shirt simply adds to the growing anticipation in the lead up to one of the most talked about occasions of the global sporting calendar.
"Seeing the shirt really gets me excited," added Davies.
"You talk to former players and they embrace the idea of the Lions jersey. They cherish the idea of playing in that jersey.
"The athlete wants to play with the Lions because it's the pinnacle of his rugby career. Players who haven't played for the Lions want to play for the Lions.
"Reading the previews before the season began, all the players simply said, 'this is Lions year'. That brings such an excitement, and an inspiration, to play rugby.
"It's a wonderful, wonderful concept the Lions. The fact that four countries should play each other during the Six Nations, with each battling and competing against each other, and then suddenly, four countries supply players to wear the one jersey, that's a terrific concept, which everybody seems to love."
