warm, but cotton

my husband in a mailman in colorado and during the winter months needs very warm clothes. i'm trying to get away from synthetic fibers like fleece that pollute our waters with plastic micro-fibers so i chose these because the are cotton. but i don't understand how you can have "super-cold-weather" cotton. the waffle-knit might insulate a little more, but not for "super cold". i think we will try wool products soft enough for a base layer.
