First impressions are that this has not been stitched together solidly enough, that the fleece material is too thin and that it's not going to be any good - but bear with...
I've worn it a lot and washed it a lot and it's still holding together - no visible damage. Well done stitches, you are solid enough!
The fleece material is thin, and in very cold temperatures a thicker hat is advisable, but for most uses this is fine.
The hat is also a strange shape - I can in fact pull the hat all the way down under my chin, so that it completely covers my head like a balaclava. "Why is that useful?" - you ask - well let me tell you. It does in fact make this hat a good sleep mask - I should say better, in fact than some purpose-made sleep-masks. Consider that, if you are a regular wearer of sleep-masks.
