Good
At 5’7” 137lbs (170cm - 62kg) the mediums fit great compared to the small. I’m not into extremely tight bibs. I have somewhat under developed legs when compared to my upper body but man do the as size small feel tight 😅 I honestly wish I could exchange them for mediums like the other pair I bought from Attaquer. The only complaint I would say I have about the Mediums is the inseam. Even though the tightness feels great, the inseam is a 2-3cm too long for someone 5’7”. Or maybe I have a longer torso and short legs than average 😅. I think size medium would fit perfect on someone 5’9” weighing 144-148lbs… assuming their body is proportional. Other than that the bib is great and the strap have plenty of wiggle room for height
