Working hard to keep your body dry and at a comfortable temperature, the MTF 4000 has you covered. MTF4000 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 are blended with spandex to increase ease of movement. The contoured fit hugs the body, eliminating excess bulk when layering, 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 cotton feel with the stretch performance of polyester.
