No matter what they say about wicking fabrics, the wool
still is dryest near my skin for me. It doesn't stink like
synthetic either.
If hiking in hot weather, don't ever wear synthetic fleece socks. Man do they stink. According to my gf, the smell was so bad it was starting to come through the boot. I've started switching all my clothes to merino wool because even in moderate activities, the synthetics really start to smell.
