These socks are without bulk warm. For me these socks do not scratch, I can no other wool as merino wool on the skin tolerated (Tip: Try before you apart from fiddling socks on the cheek if they scratch). Convenient and environmentally friendly: These socks do not need after a day out in the wash, they do not smell so easily. They fall rather small from, if you do not lean your feet, maybe they should order one size larger.
