I'll try to write a helpful review. These are good enough under-shorts but offer almost no compression. I ordered my normal size: I have a 34 inch waist at its widest point and went with medium. I was a bit worried that they might be a bit tight (based on other reviews). But the fear was entirely unfounded. They are stretchy enough that I'm sure I could put them on and still fit a penguin paperback in both front and back--maybe even a couple oranges and a banana. Not that I've tried.
The shorts work for me, but are a bit thin and don't feel anything like compression gear I own from other manufacturers. That's with a new pair. They aren't going to get tighter as they age.
Would I buy them again? Maybe. I like TSLA products, but can't consider these compression shorts. If I need a pair of normal cool dry shorts I'd consider these. But that isn't what I thought I was buying.
