About ShirtCastle
What Is ShirtCastle?
ShirtCastle is a new, independent apparel brand and online-only boutique recently soft-launched by Word Furnace LLC. We specialize in elite-quality basics and original (unusual) graphic tees, made exclusively from 100% natural fibers (excluding labels and trim).
Where Is ShirtCastle Located?
We are based in Rhinebeck, New York, where we manage all operations — from design to customer support. Our storefront is located online at ShirtCastle.com.
Do You Have a Physical Store?
Not yet. ShirtCastle is currently a dedicated online boutique, maintaining standards for quality and sustainability while shipping directly to you. However, we are built for the real world. Stay tuned for local pop-up events in the greater Hudson Valley.
Why 100% Natural Fibers?
Microplastics are now a critical human-health concern, and research identifies synthetic-fiber clothing as the primary source of microplastics in indoor household air. We trade those synthetics for high-grade natural materials that not only don’t poison you — they breathe better, feel superior against the skin, and stand the test of time. At launch, ShirtCastle features items in 100% cotton and organic cotton, but stay tuned for wool, linen, and more.
Are You an 'Eco-Brand?
Tough question, and here’s why. Many "eco" brands are big on recycled polyester. Unfortunately, recycled polyester sheds even more microplastics than regular, virgin polyester. Those fibers fill your household air, enter your lungs, and invade your organs. We know it sounds dramatic, but the research is clear. At ShirtCastle, we’re not interested in any kind of polyester—no matter how many soda bottles it reused. Polyester (and poly blends) is “banished from kingdom” by decree; inside ShirtCastle’s walls, you are safe from microplastics. It’s one place you can shop without ever having to check the tag for polyester.
Commitment to the Human Environment
At ShirtCastle we don’t claim we can save the planet. But at the household level, the danger of airborne microplastics is one crisis we can actually help remedy. Moving to a wardrobe free of microplastics is the No. 1 action you can take to reduce microplastic exposure immediately. We are here to help you protect your human environment — the air inside your home — and your personal health.
