The mummy bag states 4.8lbs shipping weight. Someone asks a question about weight on the page and the answer given is 3.25lbs. That's all the info I was able to find. link

I wasn't able to find any info about weight on the page for the backpack. On a different page for the same model, some guy said he weighed the pack on his scale, "which might not be extremely accurate," and it was 3.5lbs. link

If you have any other sources for getting your info, please enlighten us. I'm curious how much everything weighs too.
