Rated 3 out of 5 by cool itlooked a lil brighter on the pic but it turned out to look ok size fit wasnt perfect though March 19, 2014
Rated 4 out of 5 by Good quality, but tight fit I bought size L/XL since I prefer loose fitting hats, especially since it's a beanie. It surprised me how small and shallow the product is. It's more like a skull cap, designed to be worn underneath helmets or hoods like the product description suggests. Still, it appears to be good quality and the thermal lining will hopefully deliver on extreme cold days. I will keep it for now. March 17, 2014
Rated 4 out of 5 by This hat is very warm! I love my new hat, it is perfect for the Chicago windy, cold weather. It runs on the small side (I bought L/XL) but except for that it is wonderful. Love the available colors. Happy that it comes in more than just basic black and white. Will definitely buy more Columbia products. March 16, 2014
Rated 1 out of 5 by Too Tight I love the Omni Heat, but was disappointed with the Thermarator Hat. I bought three - one for me, my wife, and my son. The hats were a extremely tight fit and very uncomfortable. Returned all three hats. February 26, 2014
Rated 2 out of 5 by ski beanie Nice looking hat with no thought put into proper fit. Read all the reviews and still thought that a large size would fit. Wrong. This hat just barely fits. Ive got a nike beanie I just love.. Comparing why one hat is so much better I found that the nike has enough stretch in that it fits perfectly. The columbia hat has almost no stretch and is too small to boot. I can man handle it into an adequate fit..barely. Ive bought a lot of gear from columbia over the years and always loved the brand. So come on Columbia and start listening to your customers. Nobody wants to shell out 24 bucks for a hat that is uncomfortable. Fall out of love with this material and get back to something that works. February 20, 2014
Rated 1 out of 5 by Child Size, Not for Adults As happy as I was to find this on the Columbia site, I was extremely disappointed by the hat. The size was way too small. Not only was it too small for me, it was a tight fit for my 10-year old. I cannot believe that Columbia would sell this as a product for adults - it is a huge misrepresentation. February 12, 2014
Rated 4 out of 5 by A little snug, but does its job. Very warm and useful. Only thing is it fits a little snug. I am a bigger guy and have long hair so i suppose that could be why, i just thought it would stretch more than it really does. Great product. February 5, 2014
Rated 2 out of 5 by Thermarator Hat This product is probably very good if it fits. I got a unisex L/XL and I have a very small head (female) and this hat was very tight. So I did not keep it. It would have fit a child. January 31, 2014
Rated 5 out of 5 by Nice warm Hat! Bought mine at the store today in Black. It is a nice fit, and the fleece is soft. As well as wearing it as outer wear, I will also use it under other hats/caps including a ski helmet. Good construction and it covers the ears nicely too. January 30, 2014
Rated 5 out of 5 by A Great Hat I have owned this product for a year now and is my primary cold weather hat. It keeps my head warm without the, "skull crushing" effect from other hats. Additionally, I wear glasses and the hat does not affect wearing glasses. A big plus is the had folds neatly and can be placed in a breast pocket of a jacket. Sizing does run small, I tried a S/M but that was TOO small. By the L/XL if you are in doubt. January 7, 2014
Rated 5 out of 5 by Great product I love this hat. Very warm, fits perfectly, matches colors with my other gear. My son has one and he loves it as well. January 7, 2014
Rated 4 out of 5 by Great Hat But.... Fantastic hat, but beware, they run SMALL in size. I ordered a L/XL just because of what others stated in reviews about sizing. I do not have a L/XL head, and this hat is still a tad snug. January 6, 2014
Rated 2 out of 5 by must have been a womens large way way too small, sorry I am not able to properly evaluate the hat. January 2, 2014
Rated 2 out of 5 by Runs very small I ordered this Women's size small for my 12 year old granddaughter because the color matched her jacket. I was too small. Very disappointed. January 1, 2014
Rated 2 out of 5 by Runs too small... I have an average size head so I buy all my caps and gear online. Never had a problem before with 7-5/8ths head, but this cap is too small. I gave it two stars because the color and function are right on, but I ordered the L/XL and it ran way to small. December 30, 2013
Rated 5 out of 5 by Warm from head to toes Just used it in the mountains of TN...kept me nice and warm. December 29, 2013
Rated 5 out of 5 by Like it Fits well, keeps my head from getting cold. December 26, 2013
Rated 5 out of 5 by Tight for us with Large Heads The product is very good and very warm, however I wear a fitted 7 1/2 hat the L/XL is a little tight and only covers about half my ear. I am hoping after use, it will stretch just a tad and then the product would be perfect. December 19, 2013
Rated 5 out of 5 by Thermarator™ Hat Nice quality feels very comfortable warm product and looks/feels great. December 18, 2013
Rated 5 out of 5 by Keeps your head very warm! It's a very snug fit, however, it does a fantastic job of keeping your head warm. I LOVE this hat. Snug fit also means it doesn't shift around when you're out and about doing normal things. I used it while I was out shoveling snow and didn't have to stop to keep adjusting it at all. December 18, 2013
Rated 2 out of 5 by Runs small in size This is a very nice hat. But I got the l/Xl and it will not fit. Gave it to my 9 year old son and it fits great. December 10, 2013
Rated 1 out of 5 by hat too small I got the XL had and it is too small, I wear a 7 1/4 hat but this thing is way too small. Also, as I am writing this review is see the hat is only $16.50 and I paid $22.00 for it a few weeks ago. I think you should send me a refund for the difference!!! I am not satisfied with the fit at all December 2, 2013
Rated 5 out of 5 by Nice product I usually wear a size 7 - 7 1/4 hat, depending on the shape of it, and I was given this hat in the L/XL ( size: 6 3/4 - 7 1/2) which fits me comfortably and covers the majority of my ears. I honestly can't say that I notice any added warmth from the omni-heat in the hat, but it's still my main beanie for cold weather and light rain. December 2, 2013
Rated 5 out of 5 by Almost too warm Wish it would get colder here in NYC. Only one or two nights in 20's up to this point. Climate change is making this hat kind of obsolete in the Northeast. When it's in the 60's in November, something's not right. Hopefully it'll be a cold winter so I can use this hat to its full potential because it sure kept me warm on those cold nights. November 23, 2013
Rated 4 out of 5 by Keeps me warm I work at on the beach summer and winter. In the winter the winds turn to the north-north east and don't stop blowing until spring... It gets COLD. This hat has kept me warm on chilly nights down to 32 degrees standing outside for hours. I wish it were a little more windproof, but that goes hand in hand with it's breathability. It was a good purchase and I would make it again. Runs a little small. October 11, 2013
Rated 4 out of 5 by Good but small Same as all the review say, it does run a little small. I wear a small or medium and should have ordered a large or XL. But it is very warm and I've used it often in 10-20 degree weather (Faranheit) February 17, 2013
Rated 4 out of 5 by Very warm Just a little snug, other than that it is a great hat! Very warm and soft. February 15, 2013
Rated 3 out of 5 by Small, but good Im a big believer in columbia gear, so when I bought this hat to wear, I looked at their new omni wind Eolous and this one the Thermarator. I like them both, but the Eolous didn't come down far enough to cover half my ears. The Thermarator hat at least came down two thirds of my ears but left that last little bit freezing in the wind. Other than that slightly minor major flaw, these hats are great and Id buy them again. The Omni Heat really does it good. January 4, 2013
Rated 5 out of 5 by Love This Hat!! This hat runs a bit small, ..I would not consider my head to be be big... I'm 5 ft 4" 130 lbs and average build and I wear an XL in this hat. My husband insisted I get this hat, I was reluctant..because I usually do not like to wear hats, they are not warm or comfortable. However, when I recieved this hat, it is light weight, it fits great and I was wrapping presents and my head actually got HOT!! My daughter 11 years old wears a sm in the hat, and she loves hers as well. December 23, 2012
Rated 3 out of 5 by Need bigger sizes, size runs small? I know I have a big head (7 1/4), but this L/XL is just not big enough. It will fit on but it promptly slips off enough to not cover my ears. It probably also has to do with my hairstyle (long). I suppose if you have the same size head and a crew cut, it would stay on your head. Can't say much about how warm it keeps you as I can't wear it. Know that the material doesn't stretch that much December 17, 2012
Rated 4 out of 5 by Great item, runs small I ordered the thermerator hat and another at the same time. I immediately noticed that this this is a very tight fit for a "L/XL" and runs overall small. It is a right fit and doesn't completely cover my ears, leaving the lower half exposed. The fleece is more like a micro fleece and almost a felt material. Overall, the item kept my head, the part that was covered, nice and toasty at 50F outside. This morning, I had it at 38F and it still did well but I would consider using a hat that covered my ears better due to the size. December 15, 2012
Rated 4 out of 5 by Much too small This hat is much too small for an adult. I ordered the L/XL size, but it barely reaches the tops of my ears. After trying it on (or attempting to try it on), I double-checked the website to ensure I ordered an adult hat. I cannot imagine who would possibly fit the S/M size. It seems to be a very well constructed hat and would be comfortable for someone with an appropriate sized head. Granted, I have a larger than average head, but I thought ordering a L/XL would account for that. It does not. So, if you are going to order this, make sure you have a smaller head and order the L/XL December 5, 2012
Rated 5 out of 5 by Well Made as usual Excellent quality with a nice fit. Can't wait for cold weather to use it! November 22, 2012
Rated 4 out of 5 by good hat for outdoor conditions very warm and like that it is relatively windproof. it would help if they had size comparisons to fitted hat sizes. For example: M/L 7 to 7 1/4 L/XL 7 3/8 to 7 3/4 Etc. October 20, 2012
