The best underwear I have ever owned, comfortable, superbly tailored and well put together with smooth seams. Warm on cold winter days and nights. I do not not tolerate wool during warmer weather, so limit my use to cold winter days. Wonderful sleeping on a cold winter night with windows open. Washes well on gentle cycle (shortest possible, cold water) with mild detergent. Dry on wooden rack or towel. Wears well. Expensive, but worth the extra money. Quality and comfort are both top-notch.
