What a sock
I love smartwool socks and these are no different. A great sock that keeps dirt out on my bike. These are likely more of a road sock but these work great for MTB as well

Can't go wrong.
If you are active and are not currently in wool. You need to pick up a pair of those STAT! They really make all the difference in not having your feet get super sweaty on those long rides and you won't stick after an hour. Plus, the PhD fitting fits and feels awesome, really does make a difference. Highly recommended
