Working hard to keep your body dry and at a comfortable temperature, Hot Chillys MTF4000 has you covered. This fabric is soft and stretchy for an amazingly comfortable next-to-skin fit. The soft, spun polyester yarns are lightly sanded to give a cotton-like feel, then blended with spandex to increase ease of movement. The contoured fit hugs the body, eliminating excess bulk when layering and keeping you warm and comfortable. From the slopes to a hard day at the office, this fabric offers moisture management, UPF protection and a great cottony feel with the stretch performance of polyester.
