Swiss Gear Sleeping Bag What Is The Difference Between A $50 Swiss Gear Sleeping Bag And A $300 North Face?

What is the difference between a $50 Swiss Gear sleeping bag and a $300 North Face? - swiss gear sleeping bag

I am looking for a cold weather sleeping bag and it seems that my options are more than $ 200 for most brands, or if I have a brand such as High Peak, Swiss Gear, Kelty and slumberjack Can I choose to pay $ 60 for the Review at the same temperature. Is it really worth the extra money? I plan to take the Appalachian Trail with me so I have a good bag, but seem to be the same with most of the same components. Thank you!
