Can anyone help me find a men's full-zip sweater in cotton?

I feel like I've scoured the internet, and (excluding Amazon/Temu/fast fashion, which I don't want to purchase from) I cannot find an elegant men's full zip sweater in 100% cotton. They are all wool or cashmere or a blend.

Does anyone have a recommendation of a brand or store? I'm talking about a flat-knit or slightly ribbed sweater and not a sweatshirt or sporty style. Thanks!
