Mine weights in at about 2lbs.
The dimensions are as follows:
79 length (need to double check)
I kinda messed up with getting the right baffle height. Was aiming to get about 2-3 in of loft for it to be a 20F bag but have around 4-5in of loft which would put it up in the 10F range. So my 3 season is more of a 4 season.
