#1 Rated Cannabis Friendly Apparel Worldwide Cozy doesn't even begin to describe the feel of our fabric against your skin, and it will most likely become the softest shirt in your wardrobe. Feeling comfortable in your own skin is something we take pride in.  Our Goal at StonerDays is to support the Cannabis Community while bringing a universal awareness to the healing properties of Marijuana. Women's tanks are the perfect blend of cotton, polyester and spandex giving you the snug, stretchy feeling when you put one on. The cotton makes it soft while the polyester keeps it from fading, and the spandex helps prevent stretching. Men's tanks are 100% combed ring spun cotton cause you know, guys love cotton.
