I have bought 4 or 5. I LOVE them. They are not quite as light, but the mesh construction allows sweat to evaporate well. the underbill is perfect (light grey)
I sweat a LOT!
They wash well. I used (and washed) them constantly last summer and none have even begun to fall apart
And for the price? I can buy 5 of them for the price of ONE logo'ed hat, sweet!
