Our Colorado Tee in athletic gray is a screen printed t-shirt with a dark green water-based ink. With a retail fit, this incredibly soft t-shirt is a tri-blend made of 50% polyester, 25% Airlume combed and ring-spun cotton, 25% rayon. Our soft t-shirts are unisex in wear. How it's made: We have a USA-strong approach to production. Almost the entire manufacturing process takes place right here in America. The t-shirt blanks are designing here, dyed here and cut here. The garments are then assembled in the U.S. or Central America. All production is 100% sweatshop-free and Platinum W.R.A.P. Certified. The t-shirts are then screen printed with care in our workshop in Denver, Colorado using eco friendly manufacturing processes to minimize our ecological footprint. Washing instructions: For an optimal wash, machine wash with cold water. Tumble dry low or air dry.
