My base weight with pack, 15 degree bag, shelter, sleep pad is about 10.14 pounds, depending which shelter I take. It never higher than 10.14 with those items. To me, that is ultralight and I plan to never go above that weight with those major items. For three days, I like to keep it under 30 pounds. I have a trip coming up soon and Hurricane Sandy paved the way for old man winter to have a tail gate party in the Smokies by dumping 20 inches of snow. The extra set of clothes, extra calories of food, and miscellaneous will probably weight roughly 28ish pounds... I did an overnighter in September and August and my total weight with food and water was between 16-17 pounds. I believe that is ultralight. To others that is heavy or superlight.
