Brim went wacky before ever wearing

I too had a version of this hat about 2016 or so. It was awesome. I saltwater fish and it was perfect, stayed on in the wind with the brim flipping down in my face, dried quickly and was cool. Lost that one and repurchased an about 2020/21 and put the hat in my truck to take to the boat a few weeks later. When I took the hat out of the back seat the brim was warped almost beyond usefulness. I have to wear the hat sideways so I can see where I'm going. Very disappointed.

Missing buttons from older version

Why they choose to get of the buttons on the side of the hat ‍♂️ It's so much better when you can prop up one or both sides and go full Aussie.

It shields you from a fusion reaction

I've put it through the wringer
Size Bought:

When the holy light breaks through the clouds and shines upon earth the plants bloom, the earth wakes, and summer begins. If one is of pale complexion this is a blessing and a curse. However, have no fear this hat is made of material strong enough to shield the bold light from your eyes and scalp. Have no fear walking in the bright light of day anymore

previously great product changed to cheap copy

I bought this hat first time years ago (2017?) and found it close to perfect. Sadly manufacturer decided to save money or something and later model was not true to size, inner net was significantly smaller than hat itself and made of super rough/hard plastic, not soft like in previous models, and brim went wacky from first wash so quality was so bad i stopped buying this brand. It was the best before changes.

I returned this product before using it

I bought the medium hat for my small head and it was so small that I couldn't get it on. Had to return. Size up!

Great sun blocking hat

I've put it through the wringer
Size Bought:

These hats are extremely comfortable and effective at blocking the sun. I use them for yard work, fishing and golfing. Highly recommended

Does not wash well

I bought this hat to block the AZ sun, while the brim is large and does a good job of that. The brim became completely misshapen and twisted after one washing in an agitator-less washer and the brim now sticks up on the sides and no longer blocks the sun fully. I have tried twisting it back into shape and no go. I'll just stick with bucket hats from now on.

Great coverage and fit

Fit my big head perfectly and has great coverage from the sun. Also has good air venting which is important in Phoenix, AZ. Finally, I think it is quite stylish and has an Aussie feel to the look.

I have purchased a variety of colors over time

I do like the hat. I have a very large head, in the 7 7/8 to 8 range, and find that most of the time the XL fits. A couple of comments... 1. Most of the time they fit, but occasionally one will be a smidge too small. Not comfy. 2. I use them for golf a lot, and as I sweat during the round, the sweat stains build up and don't come out with washing. Not sure why. Maybe someone has an idea on this. 3. I think they are a good value and will continue to purchase.
