All of DRIHPs Shirts are made from Hemp. Hemp fabric holds up and wears well but also helps the environment in a plethora of ways. Hemp requires just half the acreage of cotton, and produces up to 3 times more fiber than cotton on the same amount of land. Even better, Hemp clothing resists abrasion and holds its shape, yet gets softer with every wash. It’s also naturally resistant to mold, mildew, and even UV rays! We know every Hemp shirt you buy will be your favorite!
