"How do the Clark North Americanís Insulating Pockets work?
Clark's patented pocket design locks in a stable air mass below you to deflect cold air that would otherwise cool the hammock material below your back. When you add a high quality sleeping bag, you can avoid having to buy cumbersome insulating pads and liners."
One of my friends has the NA another has a Tropical like mine. When we camp together, the NA user uses less insulation than we Tropical's do. During the summer, all of us will use nothing on the bottom. I've gotten inside the NA in the summer and was way to warm!! So those under pockets are holding in some heat. But not enough to keep you warm when the temps start dropping in the fall. And in the winter, you will need added insulation. At that point, you're not just using those pockets to "deflect cold air" but you also have the "real" air temps to deal with. The "weathershield" on the Clark works the same way. It deflects the wind and keeps some of your body heat inside the hammock.
What Clark is writing in their ad is correct but also misleading.
