I've been around the sport long enough to have seen multiple pushes in the last 15 years to move away from the singlet and to the 2-piece uniform. For the life of me, I can't understand why we can't get there. I understand the nostalgia element of the singlet for many, as well as the fact that most of us are creatures of habit. But why can't we move to a more comfortable, less revealing uniform?
A few points:
Wrestling is one of the only sports that doesn't practice in the competition uniform. 2-pieces would largely solve this. Why prepare for competition in a different uniform?
Growing wrestling is a major point of emphasis for many, namely USA Wrestling. We all want to see the level of competition in the US at the highest levels (college/senior), and how can we do that better than by lowering the barrier to entry for kids at a young age/increasing retention rates? 2-piece would help this factor by being less revealing and more practical.
There is a stigma, though I obviously disagree, that combat sports (especially wrestling) are inherently homoerotic. We can increase mass appeal of the sport by simply being less naked during competition without compromising range of motion, flexibility, and utility by implementing the 2-piece.
There are many other reasons why I think the 2-piece makes all of the sense in the world, but I'd like to hear the board's thoughts on why we are stuck with the singlet. It seems to me that the efforts to switch uniforms in the past were worthwhile, even getting as far as allowing it as a 1:1 option for athletes.
