Patagonia makes high quality gear! I got this pants from campsaver for an awesome price with free shipping. The pants are definitely more relaxed so you can layer underneath. I'm about 5'7", 140lbs and got size small. The thigh zips are a nice feature but are not meshed so keep that in mind. You can use a belt or use the velcro straps inside the pants to tighten it as well. Nice deep pockets too.
