0 sounds good. I have read about people taking the montbell SS bags down about 20dF below what is advertized with extra clothing and whatnot.
Gees I have looked at them all over and over.
Problem is there is nowhere around here I can climb into
one of these higher end bags.
I am also way out of the loop. Been using my old snow lion and kelty, Eureka gear for many moons. When I bought those older bags everything was loft with honest ratings, and I sort of had an idea of what would work where. Now its R values via clo and some crazy overstated ratings like the pounder.
My tent died a miserable death and its too heavy anyway. My synthetic 4# bag has delofted a bit, but it took 20 years. Its still a good bag though, it just went to a 45dF bag from a 35.
My old 4# down bag is still superb, but a little too short for me. Should be though it cost something like $500+ back in the 70's.
All in all it was just time for a major upgrade to lighter and better equipment.
I had a Montbell synthetic burrow bag that I returned. Got a right zip for some unkown reason, but I did like the extra flexability and room.
Thought this combo might work. The price was decent at prolite, so I guess we will see. The #7 UL 50dF long was even cheaper at $188, but this #5 is a bit warmer and only slightly heavier. I think it was $203 which I thought was a good price.
Now I just need to make the quilt.
I have a jam2 pack but I am Still working on my old Kelty pack. In 74 it was considered light then, and by todays standards its still not too bad for an extra large internal frame pack. Got the zippers working, I have stripped off some of the non essentials, sewing on some more outside pockets and loops, I rebuilt the shoulder straps, changed the metal adjsters and clips to plastic, changing the bottom sleeping bag divider to a clip type, use it or not, Same with the top center divider. Also going to make a carbon fiber frame to replace the heavy aluminum frame.
Should come in at 2.5# when I am finished.
