Hoda Hadawrote a review of Outdoor Research Echo Cap on June 29, 2013
Familiarity: I've put it through the wringer
Fit: True to size
I love these things. I have worn these caps extensively for over two years. They wick nicely, have a super light and soft fabric, and offer an adjustable fit in back with a good head band inside. The fact that you can fold the brim in half (it is 'hinged' down the middle) makes sticking it in a pocket super easy. Overall an excellent product.
The only issue I have found relates to the hinged brim. The plastic stiffener in the two halves of the brim tend to eat though the light covering fabric at the ends of the hinge after many folds/unfolds. It took me a year of wear for the plastic to break through the material and edge piping, but it still did result in holes. It would be nice if they could add a small patch of reinforcing material to the ends of the brim halves to prevent this. A dab of aquaseal could armor the area up. I may do that next.
Again, love these hats.
