This is a classic polyester Fleece Neck Tube. Made of a midweight fleece in double-lined construction, it has a substantial feel and offers plenty of warmth. We've designed the neckline at an angle, so it sits flat against your chest in the front and rises naturally to the back of your neck. It minimizes bunching and gives you a good snug fit all the way around. Everything you want a neck tube to be. 95% Polyester 5% Spandex.
