Polyester/Cotton blend. Our IMPERIAL lifestyle T is a premium fitted shirt. It has been designed carefully taking in mind the various activities we perform. The material is a blend of fabrics that lay comfortably on the physique. It has a slightly longer length than your average shirt for a more relaxed fit. The sleeves have been shortened slightly for a more aggressive look. The shoulder/neck areas have a snug fit. These shirts can be worn while performing outdoor activities or for a night out on the town.
