Fila Men's Performance Woven Shorts

What is the difference between the three types? The description details don’t seem to point to many differences, besides a “men’s back yoke”… whatever that is.

Per the buyer:

The only difference is in the aesthetics/design detailing of the shorts. They’re all the same 94/6 stretch woven fabrication and all have the same fit.

What is the length of these shorts?
