Rated 4 out of 5 by Good hat I've used this hat twice so far on my runs and has kept my head and ears nice and toasty. It hasn't been too cold her yet, 20 degrees is the coldest that I've used it for a run so far. I ran a 15 mile run and the hat came up a little bit but not enough to uncover my ears. Fits snug which is nice to keep my headphones in. It's very light weight and could easily be placed in a pocket for storage. Great hat so far. December 6, 2015
Rated 5 out of 5 by Driver Good 100% very good I recommend to!!! October 26, 2015
Rated 4 out of 5 by Too tight Cap is far too tight. Columbia should go tagless in all its products. Surprisingly warm for such thin material. October 3, 2015
Rated 5 out of 5 by Excellent Good one for winter. It keeps my ears warm February 15, 2015
Rated 5 out of 5 by Little Small First, this seems to be VERY well made. I have a buzz hair cut. I ordered a large, and it is tight (shower cap tight). To be fair however, I think "tight" is the whole idea behind this hat. February 9, 2015
Rated 2 out of 5 by Too Tight This beanie is lined with Omni-heat fabric. If it was less restrictive to the wearer, it would probably suffice. It is considerably small even for the L/XL size. January 21, 2015
Rated 4 out of 5 by Nice beanie for the weight I haven't had a problem at all with the sizing. I have a size 7 1/2 head, and the fit is "snug" (think of a competitor fit, "UA"), with a L/XL, not tight. I've worn it for extended periods with no sign of headache. It's meant to stretch, kind of a compression fit for your head, with light, stretchable material. I've looked everywhere for a beanie that will cover my WHOLE ear, and this is it. It is very light. You can stuff it in a front pants pocket, and forget it's there. My only complaint is that it isn't warm/wind resistant enough. While it is fairly warm, the lack of the omni-heat material in the lower area (which covers the ears) is a problem. That, and there is almost no wind resistance to the beanie. I plan on using it for some CO 14ers, and wind will be a factor above the treeline. Overall, not a bad beanie for its weight. I'll hang on to it and bring other options if needed. January 11, 2015
Rated 3 out of 5 by Extremely tight The cap is comfortably warm and wind resistant. However, I ordered the largest size available but it still fits quite snugly, and I have very little hair and an avg. size head. I'm hoping that as I wear it it will loosen up a bit but after 1 1/2 weeks of regular use, no luck yet. December 19, 2014
Rated 5 out of 5 by Great for cold weather! The size is right and the omni-heat liner keeps my head nice and toasty even when the temperature drops. Highly recommended January 13, 2014
Rated 4 out of 5 by Good Workout Hat This really covers your head, ears too! I primarily wear this for working out, running, cycling, etc. Great hat to wear under a bike helmet. Only issue I have is wearing glasses as head movement tends to affect wearing glasses. Not too much, but enough to be noticed. Easily washed and dried, best advice: wash on delicate cycle and air dry. Does run small. January 7, 2014
Rated 5 out of 5 by Great beanie Works great under a motorcycle helmet. December 31, 2013
