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
