Now that it is June and nice and hot here in Phoenix I thought it was time to think about when it is cold. Actually it still gets cold at night, in northern Arizona. My boys are going to Boy Scout Summer Camp, up north.

What do you folks that live in the cold recommend to carry in your day-pack to keep warm? A wool stocking cap is a given.

If you only carry one other item to stay warm what would it be? It seem that a long john undershirt might be good. Maybe a wool vest or hooded sweater.

Thanks!
