When I found out that fleece was made of plastic I instantly stopped wearing it. That is weird.
Full cotton/wool are the best.
if the writing on the tag, or the "we make it from recycled bottles" marketing material, etc didn't make it clear before that
Traditional wool is scratchier but lasts much longer. Things labeled "Donegal" tend to be of that type, but read the description, since that's the name of a town, not the type of wool.
As a sailor, I’ve also seen the mind blowing chafe/wear resistance of polyester/dacron. Dacron sails and sheets (ropes) almost never fail from chafe. No natural fiber has that kind of chafe resistance.
I love wool and hate the feel of polyester stuff, but durability isn’t one of polyesters weaknesses.
