I just spent 3 nights on the trail with my new 40 degree wide slick bag(and 1 night on a flat neoair). It is very light, i think just over a 1.5 pounds, i will wiegh it for sure later. Had a 20 degree slick bag but it was just to confining with a 66.5" girth, new wide model is 74.5". They are awesome bags, they compress down to nothing.
Bag is very warm for how thin the material is, spent a night out this winter in temps around the upper 20's and was able to make it. Not very warm and cozy but i was fine for the night with just base layers.
