I am 6"2 205lbs and a Large fits me perfectly, in fact, the Capow Bib fits me so well it feels as if I am wearing nothing when I am out shredding. The fit is stretchy, breathable, lightweight and above-all, waterproof... extremely waterproof. The Bibs also insulate very well so I typically need only one more layer underneath the bibs. The pockets are plentiful and intuitively placed for easy access to all your belongings. Pair the bib with a TREW jacket and you have an unbeatable combo.
Other than that, when you are done shredn' and ready for après, they look great when you are hanging around having a pint. Like the title says, best bib I have ever owned.
