User Review: L.L.Bean Summit 3D -20°
Fill: Polarguard 3D
Temperature Rating: -20 F
Weight: 5 lbs 14 oz.
Price Paid: $209
At just over 200 bucks and rated for -20 I would say based on nothing else this bag is a bargain. It is comfortable and easy to get in and out of as well as being tough as nails. I have only used it to -12 but it kept me warm all night long. I love this bag.
