GoLite Adrenaline (Long) 0 degree mummy bag. 800-fill goose down, ~2.75 lbs. Get a jump on the winter and buy my mummy bag! I bought this bag about 5 years ago and have taken it out for a total of 9 nights. I'm 6'6" so I'm at the max user height for the bag and thus, could not get as comfortable as I wanted so I'm selling it. The bag packs up surprisingly well, super light weight, and very warm. Always stored indoors and always hung. The center zip is comfortable for back and side sleepers alike, and the 800 fill down is incredibly lofty and warm, the foot and head zones have ripstop with a water resistant finish for wet weather or for all you mouth breathers. (like me) The baffles switch direction at about the halfway point, I'm assuming to help with warmth distribution. Whatever the reason, you can tell some thought was put into this bag. Cotton storage sack and Sea to Summit stuff sack included. My loss will hopefully be your gain. Feel free to ask any questions! Please note: I will be unable to access the internet until the day after the sleeping bag sells. So expect a short communication delay.
