ビットコイン・シャツ・コレクション

• Wash cold with like colors to keep the print crisp.
  
• Turn inside out before washing to protect the design.
  
• Hang dry or tumble dry low—high heat can shorten the life of the print.
  
• Avoid bleach and ironing directly on the design.
  

Think of it like your Bitcoin stack: care = longevity.

DTF (Direct-to-Film): The design is printed on a special film and heat-pressed onto the shirt. The result is vibrant, durable, and holds detail even on dark fabrics. Great for bold Bitcoin logos and intricate designs.

DTG (Direct-to-Garment): The design is printed directly onto the fibers of the shirt, like an inkjet printer for clothing. This gives a soft, natural feel—perfect for organic cotton Bitcoin shirts. DTG works best for detailed graphics on lighter fabrics.

• Left Chest: Classic placement for logos and minimalist designs.
• Large Center Front: Bold and attention-grabbing, ideal for statement graphics.
• Sleeves: Subtle but stylish—often used for text, dates, or secondary logos.

Our Bitcoin shirts use premium fabrics: organic cotton for softness and sustainability, ring-spun cotton for durability and a smooth finish, and poly blends (cotton mixed with polyester) for stretch, shape retention, and wrinkle resistance.

Organic cotton is grown without synthetic pesticides or fertilizers. It’s softer on your skin, lighter on the planet, and often stronger because the fibers aren’t chemically treated. Many of our Bitcoin shirts use certified organic cotton to give you a sustainable, breathable fit.

Ring-spun cotton is made by twisting and thinning the cotton strands to make a softer, finer, and more durable fabric. It feels smoother than standard cotton and holds its shape better after washing. Translation: your Bitcoin shirt won’t feel scratchy or stiff.

Poly blends combine cotton with polyester for performance: they stretch, resist wrinkles, and hold their shape—even after frequent wear.

• Oversized: Roomy, streetwear-inspired. Think relaxed conference vibes.
• Men’s Standard: Classic fit, structured shoulders, everyday wear.
• Women’s Cut: Tailored for a closer fit with shorter sleeves and tapered lines.
• Unisex: Designed to fit most body types comfortably.

Most run true to size, but oversized fits are intentionally looser. Always check the size chart on each product page—if you’re between sizes and want a more tailored look, size down. For extra lounge room, size up.

Fabric type, fit, and print method vs. embroidered, all affect cost. Organic cotton and ring-spun cotton are premium fabrics. Oversized and designer-style cuts use more material. DTG and DTF prints with high color detail also carry higher production costs. Every shirt is priced to reflect both quality and message.
