The long Jane sets hyer me through frigid air with their weight and in warmer seasons due to moisture wicking properties. I'm very happy to have found Merino Protect as purchase from other brand resulted in poor quality fabric. Merino Protect had excellent weight, fits true to size, and I've several sets which go through delicate cycle with lingerie bag and clean beautifully. A++
So glad I found Merino Protect. The warmth from the base layer has been a lifesaver through the frigid northern US winter. Best priced merino wool products around A++
