BROKIGMen's 5" Gym Bodybuilding Shorts Running Workout Lightweight Shorts Elastic Waistband with Pockets

Is it made with recycled polyester?

Do you have these shorts in white?

The pictures show zipped side pockets but the description says the back pocket is secured. Do the side pockets have zips?

if say for example i'm 34 inch waist and the Medium ends at 33, i'm wanting a tighter fit, so how's the elasticity ? or would we say L ?
