  • What is the difference between ONNOcell Bamboo and Original Bamboo?

    Original bamboo is silky and vibrant. ONNOcell has a worn look and feel. We recommend trying one of each to see which you like best - they’re both great t-shirts.
  • What size am I?

    Our shirts run true-to-size with an "athletic" fit – not tight, not baggy. If you like a looser fitting shirt or are between sizes, we recommend sizing up.
  • Do your shirts shrink?

    Like most clothes, our shirts will shrink a bit when washed in warm water and dried in the dryer. We estimate about a half-size, mostly in length. If you prefer a looser fit or are between sizes, we recommend sizing up.
  • How should I wash my ONNO t-shirts?

    We recommend washing warm or hot and drying in the dryer. ONNO shirts are preshrunk, but will still shrink a bit more. You can wash cold and line dry if you don’t want the shirt to shrink at all.


  • Why can't I find an ONNO coupon code?

    ONNO uses the highest 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 result is what we consider to be a great t-shirt – and we've priced our shirts as well as we can, every day of the year. That's why you won't see an ONNO t-shirt on sale.
