A long sleeve polo knitted in a blend of extra fine merino wool with innovative 37.5® technology. This soft and luxurious yarn is breathable and also benefits from the natural properties of merino wool. The technology helps keep your body at the ideal core temperature of 37.5°C and helps keep the microclimate next to your skin at the ideal relative humidity of 37.5%. When you’re hot, patented active particles embedded in the material remove sweat in the vapour stage before liquid sweat forms. When you’re cold, those same active particles, deriving from nature, trap your energy to help warm you up. This technology is a permanent technology that will last the lifetime of the garment since it's not a chemical finish. The fabric makes this piece equally suitable for daily wear, and a variety of active pursuits. The polo is constructed with set-in sleeves and finished with a tubular hem, ribbed cuffs, a one-button closure and a classic collar.
