I have had my Clark NA now for a week and have slept in it every night so far! I have been useing my old Marmot 10 degree bag that I've been packing for 12 years now and a light wool blanket under that, and it's been plenty warm even down to 25 degrees. Wind seems to be no issue, only slight noise with tarp even in light winds. I would not take the blanket on a pack trip but would use a pad and have not chosen one yet. Has anyone ever heard of a fatboy pad? I slept on one once and they even make sleeping on the ground comfortable, I plan to try one of these for the trail if I can find one. Discontinued I think but do have a lead on one. Anyway I'm happy with the product so far and thanks again for advice and pics for they have helped immensely.
