As your ultimate choice for a timeless base layer, Micro-Elite Chamois is a staple in the Hot Chillys brand. The descendant of our very first technical base layer in 1984, ME Chamois has earned a reputation for being the most trustworthy and sturdy underlayer produced by our company. The key to the success of this men's thermal long sleeve is the unique blend of polyester and spandex fibers. Our special formula for this thermal base layer top ensures exceptional stretch and is treated with odor-blocking properties to prevent the growth of bacteria and unwanted smells. The result is a highly advanced and high-performance men's thermal base layer top that will keep you warm for years to come! Fit Tip - Our Micro Elite Chamois products feature a snug, body fitting silhouette for exceptional moisture management. If you are in-between sizes - order up one size.
