:( I know there was lots of confusion below in the reviews for these shorts about sizing. There was some mismarked shorts in last year's run and people were all atizzy.
I ordered BOTH the size small and the size medium to determine what would work best for me. The shorts themselves are awesome. Super nice feeling, durable material, great shape to them. I was most wild about the length, not too long but not too short. Zippers seemed to be made of great quality, as did the tabs used to adjust the waistline.
I was fully in-between sizes though - BUMMER, so I returned both.
I am 5'3" and 125 lbs.
The size small looked nice, fit in the waistband and rear, looked great. BUT - I couldn't bend or squat without some discomfort, they felt a bit too tight. I typically take a size small in most brands.
The size medium was wayyy too large. It was poochy in the rear area and the waistline was huge. I could run the waistband cinches all the way down to achieve the proper fit, but it didn't look awesome. Moving around and bending they felt a LOT better than the small. But again, since the waistline and butt didn't really fit, I decided not to keep them. I wish I could have kept them.
