Bests & Worsts Reviews from Amazon

So I'm completely confused buying sleeping bags on amazon because the information is just completely wrong!! I ordered this because it said it was advertised as a 4 season sleeping bag and it isn't! the paper label on the compression bag reads - 20F but when i got the bag inside the label that is sewn into the side of the cloth reads 7-15 degrees CELSIUS which is actually 44F to 59F so don't buy this sleeping bag is you think it will be cold because it won't keep you warm!!!!
