This is a nylon bucket hat that comes complete with extra sun protection.
The hat comes with a detachable flap neck for the neck and face, along with the wide brim it fully protects your neck, face, head from the sun.
This hat would probably most suited to desert environments I think as its both lightweight and airy.
The face mask is made of a breathable mesh and a similar breathable crown, probably won't offer much rain protection.
Below with the neck and face flaps removed.
It also compacts down to a size that fits your trouser pocket.
