Rated 4.4 out of 5 by 37 reviewers.
Rated 3 out of 5 by Sizing is really weird, both too large and too small After reading the reviews that said this ran small, I ordered the next size up. It barely fit down over my ears height-wise, but width-wise it is enormous! It's difficult to keep it in place, it tends to fall forward over my eyes, but still barely covers my ears. I wish I tried this on in a store because I wouldn't have purchased it if I had realized how bad the fit is. December 14, 2016
Rated 5 out of 5 by Warm and toastie I love this hat. I have a size large head and can never find a hat that isn't too tight on my head and ears. This hat keeps me warm but I can have it on for hours without any issues. I also love that it is small enough to fold up and put in my coat pocket. I plan to get other colors. December 14, 2016
Rated 4 out of 5 by Just that bit of warmth This is great for when you just want some extra protection over your head. I do find the size slightly small. I by no means have a big head(would say im average if not slightly under average) and I find it could have been a bit "deeper" so that it stays on my head better. December 13, 2016
Rated 5 out of 5 by Amazingly warm hat This hat is amazing! I am a photographer and spend many hours in the outdoors capturing images. The first time I wore this, it was 24 degrees outside and the hat kept my head comfortable for the three plus hours I was on the bluff overlooking the Columbia River. December 11, 2016
Rated 4 out of 5 by Warm Hat I just wore this hat in temperatures in 28 degree weather with a windchill of 16. It did a good job of keeping my ears warm from the wind and cold. I am satisfied with this purchase. December 8, 2016
Rated 5 out of 5 by One of the best hats for winter weather I highly recommend this product. I use it while biking, hiking, kayaking, running in the cold weather. The reflective fleece does protect from cold weather and covers the entire ear. This hat is way superior than any other rival hats out there for winter. November 23, 2016
Rated 5 out of 5 by Thermarator™ Hat Have not used the hat for skiing yet, but plan to very soon. I have lots of Columbia products, so I'm assured of the hats quality. Fits well. March 17, 2016
Rated 3 out of 5 by DOES NOT COVER THE EARS IT IS NOT GOOD FOR COLD WEATHER February 26, 2016
Rated 5 out of 5 by So warm I love it keeps my head really warm but not that I'm a sweaty mess. They said it ran small so I ordered the larger size it perfect not tight at all which is the problem with beanies for me. the grey color is actually much lighter than pictured it looks like more of a heather when actually its a light grey. other that its great. February 15, 2016
Rated 5 out of 5 by Super warm, a little big Love this hat, very functional. February 8, 2016
Rated 4 out of 5 by For Use During Specific Cold Weather - not too cold not exactly "true to size" but based on how I bought I was not sure which side I was on. I bought XL rather than L thinking the stretch would cover me, but very limited stretch in fabric, so glad I bought one size up. keeps head warm except in wind. In MN single digit temps with a breeze, my head was a bit cool, stronger winds and head was cold. because of lack of stretch, the hat did not snug to head where the hat's edge met the head. I like the feel of the fabric on my fingers. hat was not itchy on head. function is good in the right temperature. you'll just need to find that temp for yourself January 29, 2016
Rated 5 out of 5 by Thermarator™ Hat Excellent product, keeps my head warm at low temps. Highly recommend this product January 14, 2016
Rated 3 out of 5 by Runs very small This hat is okay - it runs very small. Gave it to my granddaughter and ordered a larger one. January 13, 2016
Rated 5 out of 5 by Perfect winter hat This is the second thermarator hat I have purchased. It is the favorite hat of both my husband and my son. December 13, 2015
Rated 3 out of 5 by Runs Large This was too big for my 22" head. Be sure to measure your head before you order. According to the chart, a large should have fit fine, but this item runs large. I returned the large and purchased a small and it fits me perfectly. December 7, 2015
Rated 2 out of 5 by I prefer the Wind Bloc Beanie I ordered this in both sizes. The large one fit my head way too big. The small one fit my head way too small. They really should make this in 1) Small 2) Medium 3) Large. This "two sizes fits all" thing doesn't work on something that is not elastic or stretchy. Returning both. Glad I also ordered the Wind Bloc Beanie which fits much better. September 11, 2015
Rated 5 out of 5 by Nice hat Keeps your head very warm. Runs small March 14, 2015
Rated 4 out of 5 by Good Hat feel and fit the good. I'm not sure how the sliver lining will hold up after a few wash March 2, 2015
Rated 5 out of 5 by Nice and Warm I really like this hat. It does run a little just a little small, but it doesn't bother me. I ordered a L/XL after speaking with an associate. She told me that this hat runs a little small and she was definitely right. The hat fits nice and snug to my head, and covers my ears. I do have to pull it down from time to time, but it's not that big of a deal. I think it's cool that it fits the way it does because it leaves no room for any wind or chills to get to my head. The hat is also very warm! This hat was a great buy. March 2, 2015
Rated 5 out of 5 by A+++ VERY COMFORTALBLE TOP SERVICE March 1, 2015
Rated 5 out of 5 by Serves its purpose Great wind breaker; I live in Illinois and when it's extremely windy and cold, this hat keeps my head warm without any freezing breeze going through it. Very well insulated. Just don't look to keeping a nice hairdo after wearing it, but I guess that's the case for all hats. February 25, 2015
Rated 5 out of 5 by Warm and fits well Husband is most pleased with this product. Has a comfortable fit and is quite warm. He now wants one in every color! February 25, 2015
Rated 5 out of 5 by Great hat The hat is very warm. Love it! February 8, 2015
Rated 5 out of 5 by Great hat! Soft, colorful and warm. Very attractive hat. February 8, 2015
Rated 5 out of 5 by Very satisfied with this item. I wore this skiing a couple of days ago and it did a nice job keeping my head warm and it looked nice with my other pink attire. February 6, 2015
Rated 5 out of 5 by Warm & toasty Keeps the head warm even during the coldest soccer games, watching in the stands. Great hat! January 23, 2015
Rated 5 out of 5 by Warm for a lightweight hat Nice a toasty on top of your head. Could use a more form fitting piece on the bottom to eliminate open spaces if you have bigger ears. Otherwise great product! December 23, 2014
Rated 5 out of 5 by great watch cap I purchased this hat for my husband as a watch cap. He said that it is super warm, light weight and comfortable. It keeps his head and neck warm as the damp, cold, windy ocean air blows on him for hours at a time. He has an extremely large head and the L/XL was a perfect fit. December 18, 2014
Rated 5 out of 5 by An Excellent Everyday Hat I've never owned a hat that has left me feeling so awesomely comfortable and also doesn't leave me feeling sweaty afterwards. This is the real deal! Even though the brim of the hat comes down to a little bit below the eyebrows, I really like how my ears are covered to block those nasty winds that might howl in my face. The Omni-Heat technology in this hat will make any kind of outdoor activity more enjoyable. You won't be disappointed! December 16, 2014
Rated 5 out of 5 by Great purchace! The hat is extremely warm and true to size. Definitely recommend this hat for very cold weather. December 1, 2014
Rated 4 out of 5 by My companion The Thermarator Hat is my companion during my winter journey. As a Landscape photographer I need a good Camera and good warm hat to be out in the outdoor for a long day. I just love it!! November 19, 2014
Rated 5 out of 5 by Amazingly warm! I love omni heat it is like magic! This hat keeps me extra warm on those cold days and nights. You feel instant heat when putting it on. November 19, 2014
Rated 3 out of 5 by One size fits most, just not me I wanted to love this hat. It's warm, light, and packable. The problem is that the L/XL size is substantially too large for my 7 1/4 size head. I'm worried that the S/M will be too small for me as well, but like I said, the hat is otherwise great. November 17, 2014
Rated 1 out of 5 by Size is misleading Although the size is indicated as L/XL, it does not fit on a larger head. As far as quality and function, I was not able to use the hat, I only gave it a mid rating based on other columbia products I have used. Probably would be great on a smaller head. November 16, 2014
Rated 5 out of 5 by The best hat EVER! This hat is awesome!! My head is larger than most, i have an extra big brain, so the "one size fits all" beanies are always tight on my forehead.. and leave an impression when i take it off. This Thermorator Hat in Large fits me perfectly. The hat keeps me warm, covers my ears.. looks stylish and you can even feel the warmth inside when you take it off. I bought 4 different colors.... BRING ON THE WINTER..with this hat im set! November 16, 2014
Rated 5 out of 5 by Style and Warmth Light weight, but quite warm and cute I have a small head, even the size small comes down past my eyebrows. Definitely something that I want multiples of October 16, 2014
Rated 5 out of 5 by Great hats! I just ordered two more of these hats. I lost one toward the end of last winter and was sick about it! I've worn this hat in northern China and Mongolia and it kept my bald head toasty warm. In addition to their excellent functionality, they're great looking in sort of a rugged kind of way.
