Modern "fleece" is polyester, which is plastic-based: https://www.contrado.co.uk/blog/what-is-fleece/ https://www.contrado.co.uk/blog/what-is-fleece/

  That page even has a pair of bullet lists showing that the plastic imitation is inferior to the real thing! I do make a lot of winter trips like the one in the photograph (long winter backpacking trips) and am an instructor and I only use wool for my socks and other undergarments, and jackets. Down for sleeping in. Synthetic underpants though!

    Moths tend not to destroy microfibre polyester fleece. Other than that, a wool felt is quite nice.

      I don’t have a moth issue...my cats destroy my clothing before it can be eaten. But at least wool can be repaired.
