Rated 4 out of 5 by from Great sun protection This hat is a great tool to keep the sun off my neck and face. The neck flap wraps around and protects my ears, too. The only negative is that the top of my head gets quite warm when wearing it all day. But I'll take that so that my neck/face is protected from the sun!

Rated 5 out of 5 by from Saved my life I just spend 3 days in the Escalnte River hiking over 30 miles in the scortching heat and if it wasn't for this hat I wouldn't have made it. This hat kept the Sun off of me, keeping me cool and preventing me from dehydration. Thank you Columbia

Rated 2 out of 5 by from missing key feature Overall, quality seems adequate and price is reasonable, but I ended up returning this hat. My main objection is that the neck flap (shade) is not removable as is the case on some competitor's hats. Additionally, it can't be concealed it by rolling it up or stuffing it into the hat because the neck strap is in the way. Concerning the size, the hat rides a little low. I wear glasses and the brim interferes with my eyeglass earpieces.

Rated 5 out of 5 by from Greenhouse worker I work in a greenhouse for at least 8 hours a day. We have metal halide lights on in the winter emitting a lot of UV rays which cause me to have a winter hot house tan, not attractive. I've been wearing it in the house lately during our hot summer days when the temp inside reaches 120 by noon. The cool max shade cloth on the backside does get sweaty but keeps my neck cool and my skin UV ray damage free. I do not feel more heat from simply wearing a hat. This hat keeps me cool during work, keeps the sun out of my eyes when I can't wear glasses, and keeps the UV rays off my face and neck. I highly recommend this hat for anybody needing heat or UV ray protection.

Rated 5 out of 5 by from Absolute necessity in the summer heat! I'm an avid kayak fisherman, spending 150+ days a year on the water and have been looking for something to keep me cool and keep the sun off my neck, ears and face. I picked up the Coolhead Zero Boonie and couldn't be happier. If it gets super hot getting the fabric wet really helps cool you off. I'll be getting a couple more for gifts!

Rated 5 out of 5 by from Excellent design!! I ordered this hat just before the New England Heat Wave of July 4th 2018 and it arrived the day I was set to leave .... what a blessing my head and body remained so cool just due to the technology that went into this great hats design! Thank you Columbia!

Rated 5 out of 5 by from When cooler heads prevail! The Coolhead Zero Booney is THE hat for those hot, sunny days outdoors! Not only is this beauty well-ventilated, it is adjustable to suit average to large head sizes. Then there is that soft and comfy slim chin cord that can be dangled from the backside, as you wish. Oh, the options! The brim on the Coolhead is not a rippling nor floppy design. This one is flexible yet smartly stabilized all around. That said, you can easily roll it up and pack it away. The attached kerchief is another welcomed feature for the feather-lite feel. It gives you full protection for the sides of your face and across the lower neckline. Breezy out?..the kerchief gently flutters and still does the job. You probably will become unaware of it, but you would sure notice a sunburn! The Columbia brand stands by their OMNI FREEZE ZERO and SPF technology for a reason...they've nailed it in their clothing and accessories. Enjoy the hottest and sunniest days feeling sublimely cool with the ideal hat. Yes, it is my Go-To hat, and it is also my favorite. I chose the Fossil color and it goes with everything in my Columbia wardrobe. The Coolhead Zero Booney is fashion smart for everyone and anyone!

Rated 5 out of 5 by from Excellent For Being Out In The Sun I wear it for mowing. Light enough not to get hot and protects me from the sun. My wife doesn’t like the way it looks. I could care less. I’m all about form, function and utility. This isn’t a beauty contest!!

Rated 4 out of 5 by from Love the hat! I love the hat, it does exactly what it’s supposed to do, like keep the sun of your head and neck. The only thing I would change would be to make the brim stronger so it want blow upwards when a gust of wind hits you in the face exspossing the sun suddenly temperarly blinding you. All in all a perfect hat to work outside in. Thank you Mark Morrow

Rated 5 out of 5 by from Perfect Fit I bought this hat for my father who recently had dramatic facial cancer surgery with reconstruction and skin grafting. The side curtain panels not only provide him with protection from the sun but also have provided him the privacy he needed when he ventures out in public. Absolute home run for him to have confidence to continue life as it should be lived.

Rated 5 out of 5 by from Perfect It covers all sides of my head and neck with "coolhead"features that allow air in to cool your head but also block out the sun. Should have invested in this way earlier!

Rated 5 out of 5 by from Perfect This hat really blocks out the shade and refreshes you when in the sun. It's a complete 360 sun protection. The cooling rag is the perfect touch protects from ear to ear. It also has an adjustable strap for a perfect one size fits all.

Rated 5 out of 5 by from Amazing Hat! I love this hat! I am a postal worker, and in the heat this hat really keeps me cool. The first time I put it on, I was outside loading my truck getting hot. I put the hat on, and no lie, it felt like it cooled me off by 10 degrees. It keeps the sun off my neck and head and keeps sweat from dripping in my eyes. I really can't say enough about this hat. I bought 3 Bora Bora Boonie hats for me and my family because I was so impressed.

Rated 4 out of 5 by from Air flow. I bought this hat for summer camp in Arizona. I found the neck sun/sweat cloth restricted air flow behind my head too much, which made me hot. I ended up cutting it off. I did like the fact the brim of the hat kept its shape unlike other booney hats I own. Also the brim is wide enough to provide great shade around my neck and face. Next time I will order one with the Zerocool fabric.

Rated 5 out of 5 by from Great hat I work and play outside alot and have been using a hat with a cooling towel inside the hat to cover/cool my head and back of my neck. This hat is awesome as it does both.. No longer do I have to put suntan lotion on my ears and back of my neck (the suntan lotion seems to make me sweat even more) as the inside cover takes care of this. I would prefer that they make the inside curtain a little longer where it will cover the entire back of my neck to keep the sun off. All in all I would buy another one of these instantly. Also, I wish Columbia would make the brim of the hat a little stiffer. I find it winds up laying down after the day gets hot and you have sweated inside of the hat. I wet the inside of the top of the hat (a small amount) and it cools my head tremendously.

Rated 4 out of 5 by from Great product! I work with various people groups in Indochina to help them engage their country for community development and life transformation. In doing so, I have to serve in some pretty harsh conditions. From jungle to various urban environments- I have to have the best with me everyday. I started off researching various Hat products on YouTube. Time and again- Columbia had a better showing in almost all reviews. Thus my choice became the Columbia Coolhead Zero Booney. I don't return to Indochina until late Sept so I was able to run this hat thru it's paces at 2 different kids camps that my son was attending this summer. I was very pleased! The construction is top quality and well worth the cost. The ability to scrunch up the hat and stuff it in my sling bag was very welcome and its made to easily straighten back out and wear it with no unslightly wrinkles. I love the color and would have no problem in wearing this around town or overseas. It's very lightweight and looks great! Only 2 negatives- I really had a hard time noticing the Omni Freeze Zero tech used with this product. I was wearing this in some harsh sun and hot temps and expected some great cooling miracle and never really noticed a difference. The 2nd "con" would be that the cape hanging down the back of the hat almost trapped the heat on my neck instead of releasing it. Don't get me wrong, this hat is great for keeping the sun off of you and better than wearing nothing at all. In my opinion, it only has these 2 quirks. In closing- this hat and more importantly this company is well worth investing in!! I will definately be purchasing more Columbia products in the near future!!

Rated 5 out of 5 by from Beats the Sun and Heat I work in Afghanistan where head protection from the sun and heat is a must. This hat not only protects my head from the sun but it ACTUALLY keeps it cool too! This hat also protect my the sides of my face and the back of my neck. I get a lot a compliments about the style of this hat and how it looks good on me. All in all you will not be disappointed when you purchase this hat specifically for sun protection.

Rated 3 out of 5 by from Works, but not very convenient This product works very well for its purpose, it fully covers head and neck and there is no way to get a suntan or sun allergy wearing this. However, there are several minuses that I consider important: - the inner side of the hat is visible on the forehead when you put it on and you have to tuck it in, so it is not visible and look better on your head; - you can only wear this hat covering your neck. It is impossible to fold the neck covering material up. This would've been more convenient, since I don't need neck cover all the time when I am out. - the hat is not as "cool" as I expected. Columbia baseball hat that also has sun protection and omni-heat technology stays much cooler than this hat.

Rated 5 out of 5 by from Great Hat I have a good sized head and a lot of hair so it was great to have a comfortable fitting hat and I love the flaps for sun protection and wide brim. It makes working outside a lot more comfortable and the cooling feature is very nice too.

Rated 3 out of 5 by from Booney Hat I tried this hat on a recent day hike and would have preferred an option to remove the vertical sun shade. At times during my hike I did not need the full sun protection from the vertical shade. I attempted to roll the vertical shade up inside the hat but this did not work very well and it blocked the air vents on top of the hat. Also if you roll the vertical shade up into the hat you can not use the stampede string to secure the hat.

Rated 4 out of 5 by from Snaps or wire in the rim needed This hat is functional when you need the full rim and neck flap. When you only what the front and back rim - well it just doesn't work. There is no way to position the rim where you want it or to fold up the sides so they are out of the way. A method to roll up the neck flap would also be handy. I purchased some small plastic snaps I intend to sew onto the hat to help solve part of the issue with the rim and flap. I' haven't put the hat through hard core use yet so no comment on the cooling capabilities.

Rated 5 out of 5 by from The Coolhead Zero Booney We ranch for a living in the Colorado Rockies at over 7600 feet so the sun protection this hat provides is helpful. It feels cool as long as the back flap is wet. I wet it under a faucet before leaving the house and rarely need to re -wet it before returning hours later from irrigating. Too, its neck flap protects from mosquitoes. Because it covers the ears, I can hear them buzzing around but they rarely locate my face! Wind can become an issue and the neck strap works well with the snug fitting crown. The strap is comfortable and quick n easy to tighten or release. This is my first booney from Columbia and I agree with an earlier reviewer, in hoping the brim will not relax after repeated washing. Maintaining a straight brim across the forehead is helpful for shading, clear visibility and an attractive appearance. Thanks for producing this great product!

Rated 5 out of 5 by from Perfect for Summer Camp I bought this hat for my 10-year-old son for his outdoor summer day camp in Florida. This hat is great for extended periods of sun exposure. My son normally would burn within minutes even with sunscreen. This has allowed him to be safe in the sun.

Rated 5 out of 5 by from Awesome hat! This hat gets better each year! the Omni freeze technology is incredible on sunny days, the new back flap protects the bottom of your neck just above your collar, and as usual, the adjustable straps at the chin and the back head band allows for loose or snug fit on windy days. I purchase one of these every year for working outdoors everyday in the Florida sun and this hat has always saved my noggin from those harmful rays. my only concern this time is that this years design of the buckets material has been doubled up, two layers of the softestretch. This may prove to be more beneficial? this product has always delivered and protected! protect yourself out there! one future idea; an option to add some kind of metal or plastic wire inside the brim to help it maintain its flat circular shape through strong winds and removable for when washing and cleaning - each previous brim softens and goes limp into an "M" shape after so many washes and everyday use.
