Undershirt?

[Remington]

I wear a compression (Under Armour or Nike) tank top under my shirt. Our assigners hate when you can see the undershirt above the V-neckline of the officiating shirt and I personally agree.........but it isn't all that noticeable.

I wear standard black Under Armour heat gear shirts. The sleeves are short enough that they don't stick out of the striped shirt and I stopped caring about the small amount of black showing under the v-neck.

I used to wear cheaper UA type shirts until I finally broke down and bought a couple of actual UA shirts on clearance. The difference was enough to convert me to wearing actual UA for my compression shorts and tights too.
