If you want comfort and pretty close to the ultimate chamois, the RSE Bibs are it. I am 198 lbs and 5' 10" and 36" waist - the XL is close to perfect fit. If I wanted super compression, the Large would do, but I ride distance and I am so very impressed with these. My first Sugoi - comfortable, the chamois is not too little, not too much and is made of some awesome technology. Highly recommend for any rider, but certainly for distance. Outstanding and worth every penny!
