I need to get a sleeping bag for an upcoming float hunt in the Brooks. I've been advised to stick with synthetic fill bags. What do you all think about the Mountain Hardwear Lamina bags?
Men's Lamina 0 (3lb 10oz): http://www.mountainhardwear.com/mens...r=858#start=20
Men's Lamina -15 (4lb 9oz): http://www.mountainhardwear.com/mens...w%200#start=19
HyperLamina Torch 0 (3lb 8oz): http://www.mountainhardwear.com/hype...or=632#start=6
I have a 90lb personal gear limit. Any thoughts on which of these (if any) would be best suited to a ten-day Brooks float beginning on September 10th?
