The hat is well made and more substantial than some other high-tech rain hats.

The brim is very wide and provides terrific protection, especially in the back, where it's "got you covered".  In colder weather, the fit can be adjusted to provide room for a knitted cap such as my thin Smartwool watchcap - providing both warmth and protection from rain or wet snow.

When it's not raining, the brim can be easily folded up and "stuck" to the sides with the small velcro patches.  This produces a long (front to back) but narrow (side to side) wearing profile.  I find this works fine for not-raining conditions or walking through tight woods or brush.  The hat is also flexible enough to fold up and place in a quart-size ziploc bag for storage or carry.

I've worn mine in hot-and-humid summer conditions, and it breathes so well as to be actually more comfortable than a nylon or polyester baseball cap (my regular summer headwear).

My only quibble is that the brim isn't stiff enough to stay put in a brisk wind.  This is not a fault of the hat so much a characteristic of the type of headwear that it is.  The easily-cinched strap will keep it on your head, though.  When the strap isn't needed, it stows neatly away inside the hat, held in place by the adjustment feature in the back.

It is expensive, but all in all an unusually fine piece of protective headgear.  It received the Backpacker magazine's "Editor's Choice" distinction a couple of years ago.
