Query: ok for a liner, not recommended otherwise

I bought 4 of these bags thinking they would work well for camping when the evening temps droped to 50. Everybody in the family complained of being cold! I used mine as cover instead of a bag, the double thickness made it warm enough.In all fairness I have used it as liner quite sucessfully. I put it in a 20 degree bag in tempts of slightly less than 20. Slept on ice pack with a Thermarest pad and was surprisingly comfortable. It did feel nice to the touch.I really can't recomend this for anything other than sleep overs or a heated caabin type of camping. Using as a liner is barely acceptable, it adds alot of unnecessary bulk, your better off getting a bag thats rated a little lower than expected.
