Cyclingmastersellerwrote a review of Outdoor Research Seattle Sombrero on November 13, 2011
1. The hat is 100% waterproof
2. The brim extends in the back to keep the water from going down your shirt or jacket..
3. The hat's inner brim is super soft, and is adjustable.
4. The hat folds and tucks away in any pack
5. Best of all, if you wear glasses you will love the extra wide brim for keeping your glasses perfectly dry, even in a tough downpour.
There, I've said enough, now get off your duff, cough up the green and get yourself this Sombrero, you will thank me later.
