The North Face - Dolomite One Double

yes, it's a real thing, it's just a double wide sleeping bag made for two you'll want to find a rectangular cut one for best sizing; our north face double wide sleeping bag can separate top and bottom to be separate sleeping bags if needed

i think thats the one i have and i love it soo much i use it on every camping trip i can

Both are available from numerous retailers. I will spare anyone the hassle of trying to make a decision between the two, the Dolomite was remarkably underwhelming for me. I used it on one trip and returned it to REI and got The One bag. There are heavier duty bags out there, yes. But The One does a very, very good job of keeping me nice and toasty. I am a very early camper and I camp well into the start of ski season, my first trip in March this year we got 4 feet of snow at 12,000 feet in about 72 hours and I was very comfortable at night. It’s also very cozy. I tend to pack a lil heavy on my backpack, sleeping bag usually goes on the exterior with no issues. Oh and a note on the durability, I camp with four very large dogs and my golden retriever inevitably winds up on top or in the bag with me. No tears or scratches. I give it a good wash with Nikwax and have a giant bag of like 30 tennis balls I toss in the dryer with it and it comes out good as new every time.

I have the North Face Dolomite One. It's great for 3 season because you can play around with the temperature ratings. It has two layers on one side, for cooler temps, or you can remove a layer for warmer temps, and if it's even warmer, you can flip it to the other side which has an even thinner layer. Also, it's not a mummy sleeping bag. I can't stand feeling restricted so I have no interest in a mummy, but it's increasingly hard to find anything but mummy's these days, particularly if you are looking for something that also isn't super bulky (like the ones at Walmart that take up a ton of room and weigh a lot).
