Fabric & print quality
Comfort Colors 1717 garment-dyed heavyweight tee. 100% ring-spun cotton, 6.1 oz/yd² (207 g/m²), garment-dyed for a soft, lived-in feel, relaxed fit, twill-taped neck and shoulders.
Print: direct-to-garment (DTG) printing with water-based inks, printed into the fibers so the design stays soft and breathable. Turn inside out and wash cold to keep colors vivid for years.
Printing & shipping
Each piece is printed for you when you order, at the facility closest to you (US, Canada, UK, Europe or Australia), so there is no overstock and less waste. As soon as your order ships you receive a tracking link by email.
Production takes 2–5 business days, then delivery to the US takes about 3–8 business days. Free shipping on orders of $60 or more to the US, Canada, the UK and Australia.
Care
Wash cold, inside out, with similar colors. Tumble dry low or hang dry. Do not iron directly on the print and do not dry clean.
For everyone who has had to explain it at the museum: Mosasaurus was not a dinosaur. It was a giant marine reptile, related to today's monitor lizards and snakes, that ruled Late Cretaceous seas.
