This hoodie features our unique Grindstone Island design, which is hand silkscreened onto the garment using a white water-based ink. Water-based ink is a special type of ink that soaks into fabric instead of sitting on top of it, as plastisol does. Since the fabric isn’t compromised by the ink, the garment is left with a super soft and natural feeling print. All of our solid color hoodies are 80% cotton and 20% polyester and our heather colored ones are 50%/50%. They are breathable yet heavy enough to keep you cozy in cooler weather.
