Products & sizing

  • How do I find my size?
    Our unisex t-shirts have a relaxed fit (wider bust & longer sleeves), and are slightly longer than an average t-shirt.
    #Blockchain men - unisex t-shirts are true to size, so order your usual size

#Crypto ladies - unisex t-shirts are generally fitted for men, so consider ordering 1-size down for a flattering fit. 

To find the right size for your new t-shirt check out our size guide.

  • What are your t-shirts made of?
    We use Airlume cotton for all our t-shirts. Airlume is the highest quality combed and ring-spun cotton you can get.
        • It has 2.5x less impurities than standard ring-spun cotton
  • It uses long cotton staples, meaning less stray fibers and a smoother print surface
  • It’s dyed in L.A. using the most eco-friendly dyes and 7x less water than the average garment manufacturer

  • The only exception are t-shirts featuring the Dark Heather color, where we use a mix of 52% Airlume combed and ring-spun cotton and 48% poly.

  • Are your t-shirts really premium?
    Hash, yes! We use the premium Bella + Canvas 3001 cotton fabric, so they’re soft and light, with just the right amount of stretch.
    All t-shirts are side-seamed, with shoulder taping for extra durability, and pre-shrunk (no washing machine surprises).

    Texture details:
      • Solid colors: 100% Airlume combed and ring-spun cotton
      • Dark Heather color: 52% Airlume combed and ring-spun cotton, 48% poly
      • Weight: 4.2 oz/y² (142 g/m²)
  • 30 single yarn

  • Where are your t-shirts made?
    Our blank t-shirts are sourced from Guatemala, Nicaragua, Mexico, Honduras, or the USA. We promise you they’re 🌱100% eco-friendly & definitely no sweatshops.

    Our printed t-shirts are made in several fulfillment centers around the world, so we can deliver them to you as fast as possible - the USA, Lithuania, Spain, Australia.

  • How do you print your t-shirts?
    All our t-shirts are printed using DTG (Direct-to-Garment) printing. Through this process, speciality inks (water-based and eco-friendly) are absorbed in the fibers of the t-shirt, producing a smooth print and vibrant colors that stay true after numerous washing and wearing cycles.

  • As an exception, darker color t-shirts are printed on a white underbase, to make the colors pop. In this case, the print texture will feel just a bit rubbery - but definitely nothing like a vinyl print.

  • Why does my new t-shirt smell funny?
    It’s probably from the deodor-ants! Poor joke aside, it’s just a temporary effect of the fixation agent* that’s applied during the printing process. It will go away after your t-shirt’s first wash.

  • *Fixation agents are used for all DTG prints across the industry. They’re used to help the ink bond with the fabric, and without them, the ink would flake off the garment.

  • Will my t-shirt shrink?
    It definitely shouldn’t. Our Bella + Canvas 3001 t-shirts are pre-shrunk, exactly to avoid any bad surprises from your washing machine.
    To give your t-shirt a healthy, long-lasting life, be sure to check our printed label for washing instructions.

  • What’s the difference between unisex and normal t-shirts?
    Unisex t-shirts are designed to offer a flattering, relaxed fit to both men and women. As a result, there are a few differences between a unisex t-shirt and other cuts:
      • slightly longer sleeves
      • wider bust
      • overall longer (t-shirt height)

    That is why we recommend #cryptoladies and #womeninblockchain order 1-size down from their usual t-shirt size. Check our size guide for more details & a happy wear.


  • Who makes your t-shirt designs?
    Our t-shirt designs are created by our very own ONCHAIN Wear design crew - Vlad & Octavian.
