tcorradoThey are. I have no less than 12 pairs of them. I wear Merino wool socks year-round (live in oCal) and another nice benefit of them is that they don't stink like cotton. When traveling, it's amazing because if you pack lite like me, you can't have new socks every day.
They also have an unconditional lifetime warranty for replacement. These and SmartWool are about the only socks I wear now.
Burr0010Thanks - they look just like my others that are Merino. Well, in that case, I've not used these and can't say that I'd even try them based on the materials.
