I ran this Born Tough T-shirt today teaching a police department. No tears, super comfortable, and no sweat stains.
Check out their website for some super comfortable gear. They also have a really nice hoodie that I've been running. I'll make you another review video for that later.
This t-shirt seems to be the perfect combination between a compression (rash guard) style t-shirt and a regular t-shirt. I have some support and moisture-wicking without cutting off my circulation.
