I’m Mexican, son I’m used to tropical weathers and I’m worried about Europe winter. Here there are difficult and expensive to find thermal underware, so I don’t want to buy something that would not work.

If someone has tried different undies please let me know!!

I found some very cheap ($5)cotton-poliester 50%-50%.
Another 100% cotton ($20)
And also 100% wool ($40)

I can imagine wool is the best. . . , also the most expensive, but I can’t be sure because I’d never been in the need of using it.

Please give me some advice.

P.S. I did a search and find no similar question…

THANKS
