Perfect for rainy winter days in the Pacific Northwest
I wanted a waterproof hat with ear flaps that offered great rain protection. I first tried the OR Hat for All Seasons but the brim is not very big and didn't keep rain out of my face. It is also very warm, good in cold weather but not so good in the 40's. The Prismatic hat is perfect for my needs. The brim is very wide and offers great rain protection. It is warm with the ear flaps down and can be worn with the ear flaps up without unzipping them. In warmer weather the flaps can be taken off and the external drawcord adjustment means you always have a great fit.

Love It!
I like the farmer hat function with the tech style. Great in 25 to 40 degree air with lots of wind. Looking forward to trying it without the ear band when it gets warmer.

Zipper creates a tight, uncomfortable band.
I'm returning this because the zipper creates a tight, uncomfortable band and makes this LG hat feel small. This zipper is also a little high, making the tight part of the hat fall on the roundest part of my head, so it slips up. Can't wear a ponytail with this. I HEART OUTDOOR RESEARCH hats because they come in sizes, and LG is always my size. It's very very well put together with beautiful fabric. I really need a bill + earflaps for the dry, windy, sunny, winters where I live; Gore-tex is a really nice touch for unexpected wet weather. Would LOVE this hat without the zipper-off function!
