I've had this hat for a year or two and have worn it twice. I have a half-dozen or more Tilley hats, all of which are the same size (7 5/8) and fit well. But this one is too small and leaves a crease in my forehead. I paddle canoes a bit, but have not taken it to the water because a few hours of paddling with this hat on would give me a headache. I tried stretching it over my knee, but the stretching effect lasted only a short time.
The two times I wore it were during a light rain, for a few minutes, to see if it was water repellent. It is to an extent, with a little leakage around the hat band seam. Meanwhile, it hangs on a hat hook and looks ok. Wall art, ya know. I should donate it to Goodwill. My Tilley mashup does better in the rain. I recommend this hat because of the quality of workmanship, but would caution about the size. It runs a size small.
