Got one for Christmas, took it to Yellowstone for more than a week, loved it. I got something similar for my gal and she loved hers, too.
Soft.
Comfy.
Not a lot of tension on my big noggin.
Surprisingly warm for its light weight and thickness.
There are times, of course, when you need a more serious winter hat. (Trapper hat, rear lower skull coverage, ear flaps meeting under the jaw.) We found that these beanies were perfect most situations, with down parka hood up, or n the car, walking around in the snow without a full jacket on. Maybe doesn't block a good stiff breeze, but again, different hats for different situations.
I'm tempted to go weigh my old timey military-spec black wool watch cap to see how it compares to this, because this feels so light.
