Mammoth Double 20˚F

After a rainy 40-degree night, we both stayed completely warm the whole time—the 20-degree rating definitely holds up. The 62-inch width is a game-changer for sharing without fighting for space, and the extra room actually helps trap heat better than my old mummy bag.

We took this out on a chilly mountain night and the 20°F rating held up better than expected—my partner and I both slept warm without roasting at 4 a.m. The extra length and width make it feel less like a coffin and more like an actual bed, which is a huge plus for side sleepers like me.

The 94x62 inch footprint is a game changer—I’m 6’2” and can sprawl out without my feet hitting the zipper. Took it down to a chilly 25°F night and slept perfectly warm, no shivering at all.
