Outdoor Research WINDSTOPPER Ear Band

Great, Flexible
bought this on sale a few weeks ago and used it for the first time this past weekend while going skiing. I was nervous that it was going to be too big for my head, but because it has the velcro in the back i was able to adjust and it fit perfectly, and DEFINITELY blocked the wind. I was wearing goggles also, so it rode up a little bit on the ears, but it was easy to just pull down, and for the most part it stayed put.

only ear band I found with velcro closure
This is the only ear band that I found with a velcro closure in back, which was important to me because when I have my hair up in a ponytail, it's a lot easier to put on and take off. I prefer headbands/earbands that aren't too tight. With the velcro closure, I can adjust how loose or tight the ear band is.

Finally, an earband small enough for me
I can't tell you how difficult it has been to find an earband that isn't too loose for me. Not only does this one come in 3 sizes, but it also has an adjustable closure. I wore it today at a 5k fun run, with snow and a brisk breeze blowing. It worked perfectly. Because it needs to be snug to block the wind, the seam around the edge leaves an impression on your forehead but is comfortable nonetheless. I was so happy to find one that comes in a smaller-than-average size that I didn't care. I ordered the plum one, which actually is more magenta than it looked on my computer (very pretty color) and I might order another in black for all-purpose use.
