Thermarator™ Hat is rated 4.5 out of 5 by 77.
Rated 5 out of 5 by from Omni heat products are great Omni heat products work well with proper base and mid layer wear will keep you warm in the cold 30 degrees and below. I would recommend omni heat attire

Rated 4 out of 5 by from Untested I haven’t been able to test this watchcap yet since my purchase. I bought it for a scheduled AT hike next January. The material feels good quality and it reminds me much of my watchcap from when I was in the service. I can’t wait to try out the Omni-Heat technology to see how it holds up. I’m a little skeptical with the dots holding up through the wash but time will tell. I will update this review after putting it through the ringer.

Rated 5 out of 5 by from The Thermarator: Come with me if you want to be warm Perhaps the machines that rule the future sent this unstoppable insulating headwear to keep us warm. Very functional and durable (but would advise against putting it in a hydraulic press).

Rated 4 out of 5 by from Thermarator™ Hat Good quality! Doesn't come down over ears as far as I would have liked but it does cover them.

Rated 3 out of 5 by from Kids This seemed to be made well just very very small. Did not fit on my head, but I gave it to a 3 year old and it fit him.

Rated 4 out of 5 by from Toasty Warm But The Fit is Strange As advertised, this hat is quite warm without being bulky. The fabric has a lovely feel, and gorgeous color. My biggest problem is with the fit. I have a small head, so I ordered the s/m. It's a little snug, but that's not the problem. The problem is the hat is too large in length. When I pull it all the way down it touches both the nape of my neck and my eyelashes and it doesn't fold over where I need it to because that's where the logo is stitched in. I guess I should just hike it up, but I prefer a hat of this style to be on my head rather than above it. Still, if you need a simple and warm hat, this one's a good one.

Rated 4 out of 5 by from Keeps head warm The weight of this hat is great for those who are active. Allows your head to breath all while keeping you warm.

Rated 4 out of 5 by from Omni heat lined hat This thermarator hat was a little smaller then expected. The omni heat works to lock in warmth. Would recommend to friends and family.

Rated 5 out of 5 by from Love this hat so much, got one for each of my two kids My son borrowed my hat when we were experiencing a cold snap in Washington DC and noticed it “is technical (with Omni-heat reflective technology) without LOOKING technical.” When we got indoors he gave it back to me but I decided to get him his own hat as well as one for our daughter so they can enjoy the delicious warmth provided by this attractive hat. It’s very compact and stores well in a pocket for ready use.

Rated 5 out of 5 by from Perfit hat Love this hat so much that i have it in all colors so warm lightweight and fits perfect. It's so easy to store in pocket when weather turns on you. It's a must have and i highly recommend it to everyone who is in need of a warm hat for winter. It's also very stylish so you can wear it with everything. Get it in every color you won't go wrong.

Rated 3 out of 5 by from Warm, but a bit too small Great beanie - keeps my head warm, but it only covers to my mid ear, my ear lobes remain exposed and cold.
Date published: 2017-12-01
Rated 5 out of 5 by from Great warmth! The product is great. It’s more stylish , so it easily goes with a more dressy type of outfit. It’s warm enough that if you just wore a light weight sweater and the toboggan it is plenty warm enough at temperatures as low as 50. I’ve dealt with other brands that are made to big and they slide over your eyes or to small and don’t fit your head just right. There is no problem with this brand, it fits just right. Overall if you want a toboggan that’s nice that you don’t want to ruin at work this one will do, I’m sure if you didn’t care to ruin it it would do just the same at work!

Rated 5 out of 5 by from May as well go for Gold and get the hat too!l Bought the gloves, may as well get the hat in the same line. Matches perfectly with the rest of my apparel that I bought for winter from Columbia (jacket, gloves). The warming technology will be great this winter. Fits just great. (This review was collected as part of a promotion.)

Rated 5 out of 5 by from Comfortable and Warm! The THERMARATOR HAT is the warmest polar fleece hat I ever have owned! It meets every challenge of Chicago winters on the most windy and coldest days.

Rated 5 out of 5 by from Best Bennie I have This is my second purchase of this hat. I loved the first one so much that I never wanted t o be without one int he winter so I purchased a second. The Omni-Heat™ thermal reflective gear is absolutely top notch. I have been upgrading all my winter gear to it. I ride motorcycles year round and in Kansas City it gets cold. This gear is the thinnest, warmest, best quality gear I have ever found. I can speak highly enough for the Omni-Heat™ thermal reflective gear.

Rated 2 out of 5 by from Runs Large Nice hat but runs large. Limited to twi sizes choices of a s/m and l/xl do not allow for a good fit for customers that fall between sizes

Rated 5 out of 5 by from Cute / Warm Love this hat. Got the S/M and it fits great. Snug on my head and doesn't creep up over time even with my curly hair. Very warm, cute color. I got the bluebell color.

Rated 5 out of 5 by from AWESOME..! The hat is comfortable and super warm. Wish you had a L/XL in gray, would have bought two instead of just one.

Rated 4 out of 5 by from a great LARGE beanie Is is possible to have too many beanies when you live in cold country? I don t think so, especially with all the color options out there now. This is a great polar fleece hat with the thermal lining, but it is WAY HUGE, Even on the oversized hubby. Reminded him of the flight helmets he use to wear. Maybe if he had 3" of curly hair, it might fit better, but being half bald, he said it felt like it would fall off if the wind caught it just right or if he bent over. Other than that, its a great hat.

Rated 5 out of 5 by from Thermarator Hat I'm an outdoor guy involved with the blood sports (hunting & fishing). I needed a good cap for my urban adventures and all my other caps were camo or hunter orange in color. I decided to try out the Thermarator Hat and I was not disappointed. It is roomy and warm and definitely filled my bill for function and affordability. I highly recommend this hat to keep you warm.

Rated 5 out of 5 by from Great beanie! I was in need of a good winter beanie for some cold PNW weather and this one fits the bill quite well. I have a pretty small head (a "peanut head" according to the husband) so it was nice to find that this wasn't OSFA, which most beanies are lately. The Omni-heat lining is great and so warm! This is a great buy if you need something to keep your head warm & toasty.

Rated 5 out of 5 by from Best Beanie Ever Any Columbia product with Omni -Shield Reflective is a GREAT product ... this beanie runs large, so I am exchanging for S/M. We live at 6200 ft., so my Hexbreaker Down parka and the Thermanator beanie are a perfect pair. Columbia... consistently great for all sports !

Rated 4 out of 5 by from L/Xl is too small This is a well made hat but the fit is too small. It does an excellent job of covering my ears but the circumference is way too tight for someone who wears a size 7½ hat.
Date published: 2017-02-02
Rated 4 out of 5 by from Nice hat but too small for me. The quality of this hat is great, but it is too small for my head. Even with it pulled all the way down, it doesn't cover the bottom of my ears. I had to give it away. As long as you don't have a giant head or low ears, this hat is for you.

Rated 3 out of 5 by from 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.

Rated 5 out of 5 by from 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.
Date published: 2016-12-14
Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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.
Date published: 2016-12-09
Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
