Hmm I'm a runner and pretty much everything I wear for running is plastic. The common advice I've gotten is to avoid cotton and it's worked well for me. Anywhere I can read more about this?

Not OP, But I've read about it recently. While, I'm not yet avoiding these products, it's cause for concern.

Cotton kills, definitely avoid that.

Modern merino wool is a super material, I've moved away from synthetic jerseys entirely. Substantially less stinky, works well in all temps, and not created from plastics.

Eventually we'll understand how to synthesize something as good or better than wool, but for now merino is where it's at.

Merino wool has downsides too. It stains more easily, is more expensive, is less durable, and gets eaten by bugs. IMO it's less comfortable too.

I'd like to know who is advising you against cotton, and why? Unless you are in a strange climate it's one of the best materials for clothing.

"Cotton kills" is a common refrain in rowing because when its wet in cold environments, it can lead to hypothermia. Additionally, cotton is very heavy in water. Basic water safety used to teach that you should strip down, even use your jeans as a flotation device.

Are you saying running clothing, or just clothing in general? Cotton for running chafes a solid amount, and doesn't wick moisture well.

I've tried running in cotton and it is not a pleasant experience, especially in high humidity or rainy conditions (very common where I live).

Silk and wool breaths and keeps fresh much longer without having to wash them all the time. Wool is the best IMHO.
