I am wondering if anyone here has experience with the Kelly by Ridgeway sleeping bags. I realize the bags are NOT manufactured by Kelty Pack, only licensed to be manufactured by Wenzel Outdoors. Right now I can get a 450 Fill Power 20*f (-7*C) down bag for just over $100. I haven't been able to find the amount of fill that is used. These are new bags

My alternative is the Canadian Forces used down filled bag. These bags range from $85 - 100, depending on condition. This is for the bag only, not the complete system. From what I have seen the FP is 800 but the amount is unknown.

Is new 450 FP better than 20- 30 year old 800 FP?.

Price and packability are both big issues.

Thanks in advance for any advice or opinions,
