But Aaron was quickly reminded of one of the primary differences when he held a new jersey and playfully wondered how much more comfortable he and his contemporaries might have been had they not been forced to wear the heavy wool jerseys of yesteryear.
"I think I could play a doubleheader in this," said Aaron, who celebrated his 78th birthday Sunday.
There will be some nostalgia in the air this year when the Braves wear the alternate uniform during Saturday and Sunday home games. The cream-colored jersey design will be worn with cream-colored pants and the traditional navy cap with red brim.
The Braves had Chipper Jones, Dan Uggla and Brian McCann on hand to unveil and model the new uniforms Monday morning at Turner Field.
"It's nice to keep things fresh," Jones said. "I think everybody was excited a few years ago when we got the new blue uniforms that we wear on the road. The last few years, we've worn the red [jersey] on the weekends. I think the guys really embrace any kind of subtle change, especially one this classy. It harkens back to the days when [Aaron] was terrorizing the big leagues. I'm proud to wear it."
The jerseys will feature the traditional Braves script in red across the chest, minus the tomahawk. There will be red numbers on the front and back, navy piping, navy player letters and a new logo patch on the left sleeve.
Instead of utilizing the "screaming Indian" patch that was used in the past, the new patch will have two crisscrossing tomahawks, the year "1876" -- the franchise's first season in the National League -- and the words "Atlanta Braves."
"It is really a timeless uniform," Braves executive vice president of sales and marketing Derek Schiller said. "You could wear this jersey today, and our hope is that 10 or 20 years from now, it would be just as appealing to our players and fans."
Along with all Saturday and Sunday home games, the new alternate uniform could be worn on some special occasions.
"We're always looking for a nice subtle change," Uggla said. "It adds a little spice to our uniform."
Each of the players quickly noticed that the new jersey feels even lighter than the traditional white uniforms. This should provide a little more comfort on some of those hot and humid summer days in Atlanta.
"The uniforms mean a lot to a player," Aaron said. "These are beautiful uniforms, and I'm sure they're going to like them."
This is the club's first home uniform change since it introduced alternate red jerseys before the start of the 2005 season. The plan is to continue wearing the red jerseys for all Friday night games in Atlanta. But the Braves will likely stick with their traditional white uniforms when they host the Brewers for their home opener on Friday, April 13.
"We always want to give our fans another way to show their pride and allegiance to the team," Schiller said. "By putting out a uniform like this, it's just another way they can connect with the Braves. I think it extends our brand. Obviously there are some opportunities to sell the jersey, which is great. But the primary reason is we really wanted to create a look that focuses on the history and tradition the Braves have created."
