IK13 If you are a male, what do you wear under your uniform polo? I don’t like to button all the way up. And anything crew neck shows. V-neck…maybe I didn’t get wide enough... A-shirt/tank top doesn’t show, but it doesn’t help with armpits sweat either.
SNIPERBBB Black compression shirt since we we primarily wear blue uniforms here and that's what I use for basketball. I'm usually freezing in a volleyball gym so sweating isn't an issue.
Scrapper1 I wear a t-shirt or long sleeve t-shirt that is the same color as the uniform. But I also slide my lanyard up to my neck to keep the uniform closed enough that you can't see the undershirt.
