I'm 5'10 and 32 waist and the medium fit pretty much perfect, using the velcro tabs to tighten the waist a little. I bought these pants to walk around in snow and rain in Japan. They are well made and comfortable. I would use long underwear in temps in the 30s and high 20s. I didn't use them skiing or snowboarding and would have preferred more padded pants for that. But, overall they looks good and feel great.
