Free: Contests & Raffles.
Sval didn't say anything about EN ratings... He just said 0* bags are really 32* bags. And to use his words, anyone who "knows anything about sleeping bags" would/should be familiar with the EN rating system.
Other things to consider...The clear night sky is a -100 deg C heat sink. Make sure wherever you sleep you are obstructed from the sky - and the nylon ceiling of a tent barely counts, a fly certainly helps...Under a tree is better.Ground insulation - Thermorest or equivalent is a must. Th "R" value only applies to the "lofted fill". Between your body and the ground it goes to zero pretty quickly...Chance are you will have long johns and a hat with you. These greatly increase the effective temp range for your bag.I use a 50 deg bag with no problems for high elk in September. Weighs 1.5 lbs. I use a 20 deg bag down to about 20 deg and can manage temps no problem.You start talking 0 deg F, you better go well prepared, or you'll be dead.

I found a Marmot Never Summer zero degree bag for $180...a little less than 4 pounds. Thoughts anyone?
