So buyer bewarehonestly you will die if you try to use this in subfreezing weather

If it were warmer i would have given it 5 starsbut the seller or manufacturer needs to have a more realistic temperature rating

Posted by a reviewer on Amazon

They do advise people that the lower temperature ratings imply sleeping in full thermal clothing

Fair enoughbut if you have ever slept in a bag that was not warm enough with heavy clothes on inside you know how miserable that can be

Do not kid yourself if the weather looks like it will dip into 4550 degrees do not assume this will be enough for a comfortable nights sleep if you sleep cold

Posted by a reviewer on Amazon

For example although we expected mostly 55 degrees the temperature did dip into the 45 range

I have the jackets from ravean and they were really great quality so i suspect the liner to be up to the same standards
