The hat when I got it immediately fit me with almost no adjustments necessary. The brim holds it’s shape very well. For example I am more of a classic western ware person and I was able to bend up the sides a little bit more than they were and so far it is holding up. I was in the rain the other day and the waterproofing works very well. I will also say that if the hat did not hold its shape and even if it leaked I would still get it because I was stunned by how well this hat is made the stitching and the quality of the oil skin is exceptional I would say that hands down this is the most durable hat that I have owned.
