The Large Trainmen Bandana, also known as a Paisley bandana, is both practical and fashionable. It measures 27" x 27", which is significantly bigger than the original Trainmen. If you plan to wear it under a helmet or wrap it around your chin, we recommend this larger size. Bandana is made from 100% cotton, so it is soft and absorbent. All sides are stitched to prevent fraying.
