Proof (why mummy bags work)

Mummy bags taper at the feet and torso, which can help reduce the air your body has to warm up. The shaped hood and tighter profile also help limit heat loss compared to a rectangular bag on cold nights.

Beta Tips (real-use comfort)

• Don’t skip the pad. A good 3-season or winter pad makes a bigger difference than most people expect.
• Sleep dry. Change into dry base layers before you get in the bag.
• Vent early. If you’re overheating, unzip a little before you sweat.
• Store it loose. Between trips, store loosely to help preserve loft.

What fits inside / how it packs

• Fits in most standard stuff sacks (exact size varies by insulation type, which is not listed).
• Easy to carry in a trunk tote, rooftop box, or lashed to outer straps when space is tight.
