I absolutely LOVE this shell!
I bought this shell with the sole intentention of wearing it, all of the time, for everything. Sometimes I forget to take it off it is so comfortable. I wear it for football games in the fall, skiing all winter with layers underneath depending on the temperature, and I will wear it for spring track meets.
It rolls up well so I can keep it in my backpack that accompanies me everywhere, every day. It is starting to get a little dirty and it drives my wife insane that I won't be without it long enough for her to give it a proper cleaning. Everyone should own one!
