Lululemon What'SUP Hat

Since I like and wear my Play The Field cap so much, I decided to get another Lululemon hat!  I need one that fits a larger head and lots of hair, and the reviews seemed to indicate that the What'SUP Hat would work out.  I actually tried it on in the store just to make sure, since hats are final sale.  The store didn't have the color I wanted anyway, which was the star crushed black cherry.

I like the dark purple color, since it would go with a lot of things.  I really like this hat!  It definitely fits my big head, with room to spare!  I actually wore it to the gym for a workout already, and it was even better than I thought.  Sometimes after wearing caps for a while, I feel some sort of headache from the tightness.  But this hat didn't do that at all, which I suspect is because the back half is all mesh and it is a rather flexible material.  So it doesn't dig into your head.  Also, since the sides are mesh, it kept my head cool.  

I think I might need to get more of these hats in different colors!  I'm liking the blue one in the same print as well.  The only thing about wearing it to workout in is that it gets sweat on it, and I don't really know how to wash it.  Do you just soak it?  I don't want it to lose its shape in the washer.  Maybe I need to get one of those cap shaper things for the washing machine?  Need to figure this out.  Anybody have any experience with this?
