A man’s track jacket is also known as a warm-up jacket, or "warmups" for short, as they are intended to keep their body warm before or after sports activities, and during breaks.
A male track top is a loose top worn either by men who are training for a sport or exercising, or as informal clothing.
For men, the safest bet is to throw on a solid t-shirt under your tracksuit in black or white — though if you're wearing a tracksuit in a solid colour it might be OK to pull off a graphic or printed tee.
