The quality seems fine to me. No issues mentioned in other reviews. I'm 6' 2", 185, 34" waist and 34" inseam. I got the large and they fit perfectly. Other reviews are correct: most of the areas are completely see-through and the front is not a pouch but just a fabric covering. Surprisingly warm for how thin they are. In my opinion, these are more for a date night than for working out.
