Ok I have been using a Sierra design 15 and it’s just not cutting it. I have taken it down to around 10 degrees but had to where everything I packed in to get down there. It is really only comfortable down to around 25. I’m looking for a bigger bag (I’m a side sleeper and toss and turn all night) that I can use down into single digits without having to where my puffys. I’m looking at the two listed in the title, but would be ok with another that fits my needs. As both are semi rectangular, both from solid company’s that seem to have true ratings without being crazy heavy. I’m leaning towards the FF puffin 10 degree as it’s quite a bit cheaper. What do y’all recommend
