NIAGARA HEMP COMPANY INC. shirts are pre-washed and pre-shrunk. Hemp apparel is easy to clean. Just wash and wear. Hot or cold water, machine dry or hang dry, hemp will take any type of cleaning and keep bouncing back. Hemp will easily outlast any cotton t-shirt, getting continually softer with use. Hemp doesn't wear out, it wears in! The apparel we sell is sewn generically so there are no manufacturing labels, just the content label. Hemp will readily take heat transfers, screen printing, and embroidery. These items can be easily customized by adding your own logos, labels, or hang tags.
