The Tech Merino Crew is 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??e hot, patented active particles embedded in the material remove sweat in the vapour stage before liquid sweat forms. When you??e cold, those same active particles, deriving from nature, use your energy to help keep you warm.

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.
