Made-to-Order Graphic Apparel – Bold & Comfortable
First impression? Fire. Tenth wash? Still fire. Printed directly on Gildan® cotton with pro-grade DTG ink that bonds to the fiber. No cracking, ever.
📸 What you see is a T-Shirt mockup, but don’t stop there – this design comes in 4 different styles: T-Shirt, Long Sleeve, Crewneck Sweatshirt & Hoodie. Choose your favorite and we’ll make it just for you.
Why This Stands Out
- 🎨 Print That Pops – DTG-printed directly into the fabric. No cracking, no peeling – just bold, vivid color.
- 🧵 Skin-Friendly & Soft – OEKO-TEX certified Gildan® fabric. No harsh chemicals, just pure comfort.
- 👕 Throw It On & Go – Relaxed unisex fit with reinforced shoulders. Comfortable from morning to midnight.
- 🇺🇸 Responsibly Made – US Cotton Trust Protocol. American cotton, sustainably sourced. Quality with a conscience.
Fabric Specs
- T-Shirt (5.3 oz) & Long Sleeve (6 oz): 100% cotton – airy, comfortable, all-season wear.
- Fleece (Sweatshirt & Hoodie): 8 oz cotton/poly blend – warm, smooth surface, anti-pill finish.
- Note: Sport Grey contains a 90/10 cotton/poly blend for color consistency.
