J.B. Field'sIcelandic 30 Below Classic 70% Merino Wool Thermal Sock

They are great.

Generous sizing and great cushioning even if your riggings might be a bit tight. I wear pacs when I snowshoe and with a wool athletic sock as a liner I’m toasty. In logging boots they are the best alone.

Got these for my husband for Christmas, he hasn’t taken them off. He says they feel like very high quality, they’re thick, and perfectly warm.

These socks sag and certainly are not for really cold weather, i.e. below 32 dF. I have good circulation, so that is not the problem. Bought for sleeping, would not wear for outdoors. Will not reorder.
