These are fantastic, athletic shorts! They include a hidden drawstring to adjust the waistband, built-in liner that you feel fully covered, and a hidden zipper pocket on the backside to hold your valuables. Love the breathability and style of the shorts. It's true to size and is very good quality.
I really love MIER clothing and these shorts are another great example of why. I purchased these for my son and they are fantastic. The quality is excellent and they're clearly designed with performance in mind.
Started running and this shorts fits really well. I do like the fact it feature the side split for more leg movement while running.
I love these shorts! If you are a serious athlete or runner these are so light and wonderful and comfortable. It comes with lining but if you were someone who wanted to free ball that works too! I got a medium and they fit so comfortably!
