I decided to go on a vacation skiing in the US before the warm spring arrives.  There

Is a ski resort I found that has excellent forest and mountain hiking, Last time I went to this resort

There were many sunny days, so I always bring my nammu sun protective hat. The hat keeps my head, neck and ears completely protected from the sun, and is very comfortable on my head so I can wear it for long periods of time. I even use it in the indoor heated pool while doing laps, as I find it controls the water going into my ear when I swim. The hat is very versatile and looks good on me, as many people have commented. There was a day that was incredibly sunny and warm so I decided to not wear a winter hat and wore my nammu instead.  The nammu ht was great,  I raced down the hill, and my head was warm and protected from the wind.  I tied the hat at the back for support, so it would not fall off.  I spend my entire outdoor activities in the sun wearing nammu.
