These are literally the exact same as my lululemon shorts that I just bought last weekend for $60 but half the cost. Same back zipper pocket, same lining, same stitching, it even has the really long skinny tag like lululemon does. The only difference is the material, lululemon's shorts are 77% nylon and 23% elastane (which is the same as spandex) and these shorts are 88% polyester and 12% spandex They fit amazing, because... they are same as my lulus. According to Google, polyester and nylon are very similar except that nylon is softer but stronger than polyester. I'm waiting to buy these in every color in my size.
