I have a 35f bag that has a 60in shoulder girth. somehow I fit into it in the store. Now I find it really too tight to sleep in. when I measure around my chest and arms, it is 59 inches when I breath in. so perhaps a 60 in bag was not a smart move. fortunately I can just not zip it up fully and through a jacket over the shoulders and be fine even at 32F.

I am not looking to try some backpacking at year end where max record lows have been -3, but average lows are 23f. I am looking at a 15 to 20f bag and I have a bag liner that adds about 15f that I will take along.

I tried a 64 inch shoulder girth bag and it was better, but still not sure that would be comfortable. One old white blaze article said to add 10 inches to your shoulder measurment as an appropriate shoulder girth. that would imply 69 inches.

REI has several long wide bags with a 70in girth. I tried one in the store and it is very comfortable. it might be too big, It was the REi Radiant model http://www.rei.com/product/862474/re...t-sleeping-bag

searching on line I also see the Marmot sawtooth http://www.rei.com/product/864091/ma...h-sleeping-bag it is 63 in a regular length and 65 in a long. I'll give them a try in the store as they look to be better bags, but only if they are comfortable.

Does anyone else have a bag that has wide shoulder girth?
