  • Excellent -40 Degree


  • It's Huge Maybe 30 Liter

Best Uses

  • Antacrica Mt Everest

Comments about The North Face Dark Star -40 Degree Sleeping Bag:

It's a beautiful bag. Warm, comfortable with plenty of room. The problem is you can't carry this on your back. It's huge. Pulling a sled yes.
I talked to guy who used a -20 bag on Mt Vinson Antarctica. He's a world class pro ( seven summits, North Face Everest etc. guy( and said -40 is over kill. I'd only recommend this to a person who doesn't have to man haul their equipment.

        Comments about The North Face Dark Star -40 Degree Sleeping Bag:

        The sleeping bags are amazing. We like to camp in the mountains during winter. It usually does not go below -10 when we go. With a camping roll underneath these sleeping bags are warm and snug like you are inside. They are perfect for any winter camper. They are bulky so to get them into the stuff sack is a little tricky, but all sleeping bags are like that. Amazing bag for an amazing price!

            The North Face Dark Star is a synthetic insulated bag. It is insulated with Climashield® Prism and Climashield® Apex shingled construction. It is water resistant not water proof. Since it is a synthetic bag, if it got wet it would only loose 30% of it's insulating properties if it gets wet.
