I was looking at pictures of all the kids in my old neighborhood, growing up.
One guy was the star of the basketball team and just like the varsity tanks,  I grabbed the idea for these shorts straight from his uniform.

I just made them sexier by shortening the inseam to 5", trimming up the leg and cutting it in a sexy micro-mesh fabric.

The micro-mesh is a silky-smooth polyester that has been perforated for extra breathability.
This has become my go-to workout short.
