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.

ONNO shirts are preshrunk, but will shrink more when washed warm and dried hot.

We estimate about a half-size, mostly in length. If you prefer a looser fit or are between sizes, we recommend sizing up.

We estimate about a half-size, mostly in length. If you prefer a looser fit or are between sizes, we recommend sizing up.

So feel free to wash warm and dry hot if some shrinkage is okay with you. Or wash cold and hang dry if you don't want any shrinkage at all.

If you're new to ONNO, start with bamboo and beechwood (or lyocell for men). Yes, both!

Bamboo, beechwood, lyocell, and organic cotton are thinner fabrics.

If you want a mid-weight fabric that is less revealing, try pima cotton and hemp.

We decided to price ONNO t-shirts right every day of the year.

This means you don't have to search or wait for a coupon code, or wonder if you got the best price.

It also means you don't have to wait if you need new t-shirts : )

The word ONNO is of Dutch origin and is related to the word “generous” which is a core value at ONNO.
