The hemp plant grows well without using pesticides or other agrochemicals. It is a hardy plant that can withstand harsh weather, and fertilizes its own soil by shedding leaves throughout the season. These natural qualities make hemp a sustainable choice for the production of many goods. Hemp is illegal to grow in the U.S., so hemp fibers must be imported for use in the apparel industry. It is not illegal to use hemp in manufacturing—hemp oil is an ingredient in many cosmetics, and hemp paper and clothing are sold in the U.S. Hemp fabric is moth-resistant, quick-drying and holds its shape well. Though difficult to bleach, it can be dyed a variety of dark and bright colors. It is breathable and durable, and becomes softer through washing and wearing.
