These are second pair of shorts I got for my husband from Gititlys and both fit well. My husband is between L and XL, I got him XL and they fit him well so I tell for certain it's true to size. He wears them to gym and he said that they feel comfortable and don't restrict his movements. He does squads and all at the gym and I dont see any signs of inseam getting undone. Fabric is thin, light, doesn't keep my husband hot/warm and it dries fast. Overall I am very pleased with my purchase, they are well made with nice and even stitching, they haven't shrunk or faded after washing and drying. I wash most of our clothes in warm or cold water and dont keep them in the dryer for too long to prevent fabric from fading and shrinking.
I can tell that my husband favors those short a lot because after I do laundry they are the first 2 pairs that he wears to gym
