+1Look at Big Agnes bags. I have two a negative 20 and a zero. I get cold easy. I choose the ones with sleeves for the pad so you don't role off the pad. Mine has no down under you only over you so you sleep directly on the pad. This lightens the bag.
Like a fool I left my Western Mountaineerig bag to try a new bag.
Western rates their bags for sleeping naked.....others assume you'll run in place wearing all your gear.
Yeah, I've seen those studies that say sleeping naked actually keeps you warmer in a good bag, I don't believe that.sleeping naked on the side of a mountain is awesome!
For some reason REI gets overlooked by hunters, but I would check out their magma 15 bag. It’s probably the best value in a piece of gear that I own. It’s an 850 fill and weighs less than two lbs. Very comfortable and definitely lives up to its temperature rating.
