We're looking at two sleep systems - One for the "shoulder" seasons of spring and fall on either end of the trail, and another for the dog days of summer. The shoulder system needs greater insulation - both from the air, and from the ground. Sleeping bags, rated for 15 degrees, with insulated sleeping pads are prescribed. We'll dedicate a pair of dry socks to sleep in. On colder nights, we'll wear any clothing required to supplement the bag!
