Celebrate the anti-microplastic creed with the ShirtCastle University Seal Tee. Looks great alone or under a blazer.

Description

The ShirtCastle University Seal Tee is a black, premium-quality, 100% heavyweight cotton T-shirt printed direct-to-garment on front and back, with the seal of the fictional ShirtCastle University on the back and a detail of the seal's crest on the front left chest. The seal's Latin slogan Nullum Plasticum in Corpore means "no plastic in the body" — a nod to wearing only natural-fiber clothing to rid your human environment of the insidious airborne microplastics shed by polyester.

Thank you

Your ShirtCastle™ University Seal Tee is made especially for you when you place an order, so it takes some extra time to produce and deliver it. Making shirts on demand instead of in bulk helps reduce overproduction — so thank you for your patience and thoughtful purchasing decisions.

Why No Polyester

Your ShirtCastle™ University Seal Tee is made from 100% cotton and not a poly blend. Here's why that matters to your health.
