I am looking for a thermal base layer top.
Everywhere that I look online, it's all polyester and arcylic fibres.
I hate these in clothes. I lover natural fibres.
I checked for wool base layers/Merino but the prices are too expensive. Some of them even nearing 80 pounds and it's too much.
Would a long sleeved cotton t-shirt under my clothes work as a thermal base layer?
I will be going to Poland next week and it will be cold.
