I'm working up to wearing this one... maybe next year!
Oh, and I'll have gloves, just in case, in the Hydrapak. Even 11,453ft near treeline has a forecasted high of 57. But they're useful for the Descent too.
I'll also be wearing a hat, but not sunglasses. I find shading my eyes coming down useful above treeline, but need to see roots and rocks in the shadows on the Descent.
