Frequently Asked Questions (FAQ)


Q: What makes Zendorphin Design t-shirts different?

A: We focus on clothing that is suitable for both your workouts and your daily life. Rather than selling a basic and cheap cotton t-shirt, we use tri-blended t-shirts from manufacturers like American Apparel and Bella+Canvas. These shirts are not only extremely soft to touch, but also suitable for working out. The shirts also feature a more athletic fit than regular shirts.

Our tank tops are made from either jersey cotton (men’s) or tri-blend materials (women’s), which is more durable and softer than regular cotton. These tank tops are from manufacturers like American Apparel and Next Level.

Lastly, we are a veteran and minority-owned business that only uses shirts and tank tops from companies that have a commitment and track record of ethical standards and conduct. Our current line-up not only reflects quality, but also a responsibility to international labor standards and environmental stewardship.

Q: Are there any special considerations when choosing a size?

A: Based on our customer’s feedback, here’s what we recommend:

  • Women’s and Men’s tank tops: Tend to run a slightly larger, so recommend ordering a size smaller than your normal t-shirt size.
  • Women’s and Men’s t-shirts: Tend to be true to size (though with a modern and athletic cut), so order your normal shirt size.
  • Unisex long-sleeve shirts: Tend to be true to size (though with a modern and athletic cut), so order your normal shirt size.

Q: How are your t-shirts produced?

We use an on-demand (drop-ship) printer to create our shirts, which allows us to serve our customers around the world and offer a variety of colors. Since we don’t have to print and maintain a large stock, we can keep our prices competitive and continually update our product line. The same company that prints our shirts also ships them, which helps make the process faster and more efficient.

We are located in Los Angeles, California. All of our printing and shipping is done in the “City of Angels”!


Q: How much is shipping?
