• Can I change/cancel my order? Since we ship very quickly (same day in most cases), we may not be able to cancel an order. But if you’ve ordered in error, please shoot us an email and we’ll fix it!
  • How long before my order ships? We ship within 1-2 business days. If you have not received a confirmation email after placing your order, please let us know!
  • What forms of payment do you take? We accept all major US credit cards (Visa, Mastercard, Discover, Amex) as well as Paypal.
  • What are your shipping methods and how long do they take? We ship via the USPS. We find them to be the most cost-effective and fastest way to get your new shirt to you. If you need a rush shipment, or you have an especially large order (more than 5-6 shirts), please contact us at us@onnotshirts.com and we’ll arrange the best way to send it.
  • How much does shipping cost? Shipping within the United States including Alaska, Hawaii, and Puerto Rico, is free and fast. International orders cost a flat rate of $5 per t-shirt, anywhere in the world. 
  • Where is my order? To track your order please log in to your account and click on [“order history”] For orders marked as “delivered” but not received, please contact USPS.
  • Do you offer gift cards? At this time, we do not. But, because of our Happiness Promise™, you can send a t-shirt (or two or three!) to someone you love and rest assured that they will be taken care of if they don’t like it.


  • What’s the “Happiness Promise™”?: ONNO wants you to be happy with your new shirt. Simple as that. Need a different size? Don’t like the color? Damaged when it arrived? Let us know and we’ll work with you to make it right. Drop us a line at hello@onno.com and include your order number.
  • When can I expect my refund? We process refunds immediately but most banks take two to five days to post them to your account. If you haven’t received your refund after five business days, please let us know.
  • How do I return a gift? Just email us at hello@onno.com. Include the order number if you have it, or the email of the gift-giver if you don’t.


  • What size am I? Our shirts run true-to-size with an “athletic” fit. Not too tight, not too baggy. If you like a looser fitting shirt or are between sizes, we recommend sizing up. Keep in mind that, like most garments, our shirts will shrink a bit. We estimate about a half-size, mostly in length.  If you like the size of your ONNO t-shirt, please wash in cold water.  If you want it to shrink a bit, feel free to wash in warm or hot water.


  • Why can’t I find an ONNO coupon code?  ONNO uses the best quality sustainable and organic fibers we can find.  Throughout the sourcing of our fibers, knitting, dyeing, cutting and sewing – we are focused on making the best t-shirt we can, and paying people well along the way. Saving money is not our focus. The end result is what we consider to be a good (actually great) t-shirt – and we’ve priced the t-shirt as well as we can, every day of the year. That’s why you’ll never see an ONNO t-shirt on sale.
