    Your nose should only be pink from attacking the altitude, not from sunburn.

    Whether you’re trekking through the mountains or fighting your way through crowds of tourists, adventures abroad should never catch you without proper headwear. The Outdoor Research Sombriolet Sun Hat, complete with foam-stiffened brim floats , keeps the sun off your head during ray-intensive explorations. A mesh-lined crown and moisture-managing headband help keep you dry, while crown vents let you cool down the think tank when you’re overloading on the gorgeous views.

    Texas Tested

    I just got this hat today and took it out into the Austin afternoon for a test drive. The temperature was about 103 and the heat index a balmy 114, and this hat performed excellently. It kept the sun off my pate. It shaded my neck and face and all around my head. And it was the lightest weight and most comfortable hat I've ever worn. I think I've found me the perfect hat for the screaming sun of Texas and the more mellow, but just as dangerous sunshine of Santa Fe.

    This is a schweet hat. The size fit my big ole noggin perfectly. Brim is big and has a lightweight but durable core to prevent it from becoming wavy. Also it does a nice job with sun protection and not making my head feel to hot. I intend to use it for backpacking also. Tested it and noticed the back of the brim touches the top of backpack at times but was able to flip the back of brim slightly upwards and it holds in place. That small amount of impedance with a hat hitting your BP can be a real pain in the neck. I'm using a 48L pack so its not that tall. If you have a tall pack you may find it difficult to wear this when on trail.
    Overall this is a great light weight product! Does everything its supposed to do and comes highly recommended

    This is the one!

    Finally a hat that fits my giant head....I'm a size 7 1/2, which doesn't seem to be too big, but for whatever reason I am normally unable to find anything off the rack that fits...

    I recently lost a 60 cm Columbia bora bora that fit tight and did a decent job, and decided to try again with something new.

    So glad I did!

    Bought this in XL and I actually have a hat that doesn't feel like it's cutting off blood to my brain while making me go bald at the same time.

    The brim is huge, a solid 2 inches at least wider than the Columbia, and also keeps it's shape which I like. (The floppy look wasn't really my thing.) This has an Australian look to it, not sure how else to describe it.

    My neck is covered, my forehead is covered, everything is covered!

    Well made, comfortable, breathing vents all the way around, this thing is fantastic...well worth what I paid and I'll do it again if need be.

    Shipped quick, couldn't be happier really.

    If you are on the fence because of the price, jump off and just do it.

    Your head will thank you.

    Thanks Outdoor Research!

    Live in Southwest Florida sunny and hot , keeps sun from burning your head and ears . Would recommend to anyone who enjoys the sun or works in sun .

    Yes, this is the hat you want

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    Yes, this is the hat you're looking for. If you're like me - you've been hunting and researching a while. The versatility of this hat is unlike any other and this is the one you want!

    Big ol' brim!

    • Familiarity: I've used it several times

    This hat is ideal for days on the river where the sun is blistering down from above. The brim is HUGE! which is awesome. The shade this thing provides is unmatched to any other hat i have had. borderline sombrero with a little more style points.

    Biggest Brim I Could Find

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I've been wearing one of these hats for several years now. I'm a window washer that works in the sun 3/4 of the year, All day everyday. It really protects with its 50+ Rating and huge brim. Not only does it protect my bald head but my nose and neck too. Wearing this has been much nicer than having sunscreen in my eyes all day. It breathes really well and doesn't overheat me. My only drawback is that it stains from sweat over time. But with the amount of wear it gets I think that's inevitable. I think this is my third one in 9 years.

    It runs true to size but I buy them large so they sit lower on my head

    Loved my camo so much that I bought 2 more: one Sand colored and one OD Green. Quality workmanship, rain resistant, cool in the heat, acceptably warm in the cold; THIS HAT IS A "Daisy"....

    Giant shade .

    • Familiarity: I've put it through the wringer

    Sweet hat great for keeping the sun off your neck and face. I find it very breathable and easy to wear all day on hot days. I wear 71/4 hat purchased a medium. Find it a bit snug but not uncomfortable . With the draw string cord on the back if you are debating on a size go up a size . You will be able to snug it down no problem .

    Big Bad Brim

    • Familiarity: I returned this product before using it
    • Fit: True to size

    The brim on this hat is huge, just as advertised. It would be perfect for spending all day on a charter boat catching red snapper with a few buddies. They wouldn't make fun of your big hat for very long and the coverage would be fantastic. But for other pursuits I felt this hat was too big for me and a little obnoxious. I returned it and got the OR Helios Sun Hat instead. Totally a style preference and couldn't be happier with the switch.

    I have both the Sombiolet and Helios and agree with LeeH's assessment. I think the helios is a perfect knock around sunhat; however, I found the stiffer (albeit goofier) brim of the Sombriolet holds up much better in the face of any kind of breeze or wind. For this reason, i end up wearing the Sombriolet 90% of the time.

    Great Hat for long days in sun

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I've had this hat for two years now. I love the asymmetrical brim as it keeps the sun off the back of your neck while not obscuring your forward view. I also like how the hat vents as I tend to end up with a wet head from sweat in my other hats. I will say that if you pack this tightly in a bag, it may come out somewhat misshapen. It will return to its normal shape over time, but the support for the brim seems to learn whatever shape its stored in.

    Bring on the sun

    Great hat. Very lightweight and breathable mesh liner. This hat has a wide brim, that is neither floppy nor stiff but a perfect mix of both. It holds its shape, and keeps you protected from the elements. From working outdoors as a lifeguard, to lounging at the beach, canoeing the rivers of Maine, and hiking the peaks of NH and VT, this hat has been able to do it all. It can be folded, or tied to a pack when not in use and easily stored. Wind poses a potential problem, as the brim will blow upward and leave your face exposed.

    Bring on the sun

    Great Lid!

    • Fit: True to size

    This hat is great. It has a nice wide brim to keep the sun off your ears, face, and neck. I took this hat while I was hiking Kings Peak in Utah and it rained on us the whole day. This hat is water-resistant, but not waterproof. However, the brim did a great job of keeping the rain off my face and it allowed the water to roll down the back of my jacket as I was hiking. The mesh ventilation is nice as well. I haven't felt super hot in this hat yet (which was initially a big concern of mine). Love this thing!

    Outdoor Research Sun Protection Products

    If you're not careful, long days outside hiking, paddling or climbing can leave your skin damaged and burned. To keep you protected from damaging ultraviolet rays, Outdoor Research offers a full line of sun hats, and UV Protective shirts and pants designed to keep you protected from the sun.

    Great Hat

      This is the best sun hat I ever owned; and I've owned my share.

      I added a strap to hold my hat more secure against wind from the rear. It's simple, you might want to try it" Using the same chin loops for the front, I tied 2 mm paracord to each loop (behind the existing strap) with a half hitch, lifted the strap -- dangling the hat -- cut the cord at it's apex -- then over laped the two ends with a half hitch on each side.

      It now can be adjusted in tightness to compliment the already good cinch on the back of the hat.

      Great Hat

        I wear a 7 1/8 to a 7 1/4 fitted hat size. I went with the medium I could have gone large and used the cinch strap, but the medium stays on my head with out causing any discomfort. I've worn it for a few weeks now on numerous 8 and 12 hour shifts working outside, and have been pleased. This hat has all the qualities that the previous reviewers speak of.

        Great Hat!

          I bought this hat 3 months ago. I am an Assistant Scoutmaster with the Boy Scouts and after a few outings in the hot sun I decided I needed something better that would block the sun and provide ventilation at the same time. This hat does great at both. I wear it outside working or playing, when I mow, and a week at summer camp. The brim is wide enough to block the sun. The four vents are great for allowing air to flow through, helping to keep you cool. The hat does have a stiff rim around the brim, but I can still roll it up and pack it away when I need to. It also has an adjustable draw string to adjust the fit of the hat.
          My brother likes it so much that he ordered himself one. Another of the Assistant Scoutmasters is getting himself one also. I have recieved a lot of positive comments about the hat. I would definitely buy this hat again. I also recieved great service from

          Excellent hat

            Ive always worn visors while backpacking, but thought I would try this one. I love this hat in the summer for backpacking. It rarely leaves my head. Its coverage is perfect, large enough to shade my face and neck. It breathes very well and I'm cooler with the hat on rather than off.

            Will the vents let sun through? I worry that my bald head will get burned where the vents are located. Fair skinned and even with sunblock I will burn. So, will i end up with streaks of sun burn where the vents are, as many hats will do?

            Best Answer

            I'm not sure exactly what your question is, but yes, this hat is designed to provide both sun and water protection. River rafting or hiking in an area known for afternoon thundershowers are a couple examples that come to mind for it's use. Portaging kayaks would combine both of those examples in one activity; it's a versatile piece of headwear. If you are looking for even more protection from rain in a sun hat, look at the OR SunShower Sombrero, also sold here at BC. Hope that helps.
