Same! Though I did just buy a sun sweater made of modal (beech tree rayon) that seems really nice, although it's technically synthetic fabric because of all the processing. Waiting for it to dry before I actually try it on, but I really liked how it felt in my hands.

One outlier is a really old polo sweater that has this really smooth liner that I'm quite certain is entirely polyester but made with really thick strands weaved together. I don't wash it much which is probably why it's more than a decade old now and still in one piece.

Other then those two items everything is cotton. I find levis are the sturdiest and sometimes comfiest jeans if you get the baggier versions.
