OK, this is something I don't find mentioned much on forums or in the books.
Experienced distance hikers out there.... what's the most comfortable solution you've found for undies? Microfiber? Built-in? I'm trying a pair of Barely There and I like them a lot. I also like running shorts with the built-in moisture-management liner. Cotton is awful. Nylon is worse.
Do you take 2 pairs and wash-one-wear-one?
