I have to buy a Men’s t-shirt to get one to fit, although it is a bit long. Female UK size 18, Seadon size Men’s size XXL.

The sizing defaults to Small if you change the colour so I got a Small by mistake (which would fit a 12 year old). I don’t intend to even try to return it.

Please sort out your sizing and make sizes for full size adults.

Looks great, slightly long, though awesome shirt.

Washed this morning, hung up and already dry! Husband likes that it's thin enough to layer under shirt and it's soft. (hasn't worn it yet). The color was not white as hoped. He sized up from his regular M and the L is perfect so it's a smaller fit.

This T is very comfortable, fabric is soft, and very breathable. It might run small for some people, but the fit is perfect for me. I prefer wearing this over my cotton T's.

Acquired for a Scout troop trek to Philmont. Lightweight, comfortable, quick to dry when sweaty, and remarkable odor-deterring. Sizing seems to run loose enough in the torso, but more snugly in the arms. Scout normally wears a size large, but felt constricted in the arms, so we sized up to XL. Seadon was very good about dealing the return. Looking forward to using the XL at Philmont scout camp.
