About Us

NorCal Grown Apparel is excited to bring you this sensational line of cannabis-inspired t-shirts, based on the artwork by the incredibly talented Pat Ryan. We are thrilled to offer you these fun, humorous shirts on high-quality, 100% cotton.
Located in beautiful Humboldt County, California, we have been printing t-shirts under our screenprinting business name “Mattole River Studios”, for over twenty years. The NorCal Grown Apparel t-shirt line is proud to be hand-printed in Humboldt by Mattole River Studios.

Contact us for all your screenprinting needs. We offer custom designs or we can print your design.  From concept to completion, no job is too big or too small. Check out our web site and many of our great clients at Mattole River Studios.
