Running Shorts have zippers on both side pockets to include a liner allowing to rock these shorts straight commando. The body material is that of our Athletic Shorts aka Loungers and just as comfortable allowing more sun to cress the thighs; the liner is a very comfortable mesh that isn't overly tight but does the trick.
Sizing is 'True to Size' and our size chart is accurate. The waistband on these is identical to our Athletic Shorts so if you're dialed in on those then you're good.
While some customers wear the same size in their Athletic Shorts, the liner adds a thin layer which might cause you to go up depending on the fit that you prefer.
