4.5 out of 5 stars. Order one size larger.

I normally wear a 7.75" (~60cm) hat for hiking. The Tropic XXL (3XL) hat fits pretty much perfect. Thus, I recommend to order one size larger than normal. I currently live and hike at 6.5K+", and sun protection is critical. You wouldn't think that altitude makes such a difference, but it does, "trust me."

For hiking or survivalist/ bug out bag, this is an excellent hat if ordered one size larger than you wear.

For comparison, Magellan XXL fits perfect, Dorfman XXL is way too big and heavy. "Asian" manufactured hats are two or more sizes too small at the minimum.

Tropic 3XL covers my tshirt or tank top neck , and about 3/4 of ear. It is not completely centered, so some dorkyness may occur ... but, if you are reading this, you don't really give a f##. It is close enough for  anything from apocalypse to golf course. Good eye, back neck, and upper face shade; I would still recommend SPF on neck, ears, and shoulders. The neck flap is completely opaque, but not weighty... although I have yet to wear it in humid or sweaty conditions. You will have to "adjust" the flap, it doesn't just hand loosely, there is a little bit of bunching behind the neck that tugs out in a jiff.

For real, I am ordering another, first for hiking, 2nd for SHTF bag
