Brand new here and I have searched around a little, but not finding what I'm hoping to find... Looking to try and find a 20° sleeping bag for that's around 2lbs but with a seemingly impossible budget of $150... And the other factor is I'm 6'2 so seem to need the long sizes. Is this even possible? Am I going to be limited to buying used? Is there something that's close that might work? Thanks in advance for any input.
