Merino wool is a natural fiber grown by Merino sheep. Merino wool is highly accoladed for helping to keep your body at a stable temperature. When it’s cold outside, the natural fiber matrix traps air, insulating you. When it’s warm outside, it transports sweat quickly away from the skin, helping to keep you cool and dry. Noticeably soft and refined, with BENTLEY, we welcome a new era of polo excellence.
