Thank you

Your ShirtCastle™ 4% Neanderthal 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 reduces overproduction — so thank you for your patience and thoughtful purchasing decisions.

Why No Polyester

Your ShirtCastle™ 4% Neanderthal Tee is made from 100% cotton and not a poly blend. Here's why that matters to your health.
