I'm really not trying to be pissy here but !
I really do not understand when folks give a number for their pack wt. This morning I took my gear out of the closet, wanted to know what the whole thing weighed. The temps have dropped so I started with winter gear. 22 lbs or so, I realized I left out a few things, like a gas stove will weigh 2x the weight of a canister stove, not insignificant, but necessary at much below freezing. a couple of other things. I added 2 lbs. 24 lbs guess.
Then I pulled out the winter sleeping bag, added the summer bag difference, 1 lb, pulled out the down jacket and heavy fleece 3 lbs close. and a couple of lesser things. So the summer pack wt. dropped 5 lbs +. Spring wt. probably 1/2 way between.
I added boots, t shirt etc. to get skin out wt. back up to about 24.
So really what are you talking about when you say pack wt? I seems what time of year it is makes a great difference.
