      Huge and warm!

      I panic-ordered this bag when I realized that our Thanksgiving camping trip was going to be *cold*. It is *massive* -- truly queen sized -- and a bit on the hefty side (as the specs say, it's over 15lbs). Still, it was quite warm and very roomy for myself (5'6") and my husband (6'2"). He is an especially restless sleeper when we camp, and he had plenty of room to toss and turn without affecting me.

      The only issue really is that it's nearly impossible to get back into the compression bag. It took the two of us a half-hour and two bungee-style straps, and you can see in the photo how far we got.

      Thank you for taking the time to review our product! It sounds like the sleeping bag was a great fit for your Thanksgiving camping trip, offering both warmth and ample space. Regarding getting it back into the compression bag, it can take some practice and two people! From your pictures, it seems you tried rolling the sleeping bag, which is a bit tricky. The best approach is actually not to roll it, but to fold the sleeping bag in half lengthwise and then stuff it directly into the bag. We have a helpful video on our YouTube channel demonstrating this method.
      If you need more guidance, our Customer Experience team is always ready to assist. Feel free to reach out to them, and they'll be happy to walk you through the process. Thanks again for your feedback, and we're thrilled you enjoyed your camping experience!

      Nice - But Can't Pack It Up

      My wife and I shared this sleeping bag in the mountains recently when the temperatures dropped to the high 30s in the morning hours. The bag is very thick, warm, and comfortable with soft fleece inside - so far so good.

      In case you didn't realize, this sleeping bag is huge, more than double the size of two mummy-style sleeping bags. But when we needed to stuff it back into its stuff sack, fuggetaboutit! It's almost impossible to stuff inside. I suspect the root cause is that the man made loft won't compress as tightly as down. You've heard of the expression "trying to stuff ten pounds of **** into a five pound sack?" Well, the expression takes on a new (literal) meaning here. With my wife's help we finally stuffed it back in the sack after 20 strenuous sweaty minutes.

      Back home I opened it up and aired it out, but the problem remained. What to do? Others have written about getting a larger stuff sack, but the current (stuffed) stuff sack is already huge, and we didn't want to create yet a bigger monster.

      The (sort-of) answer to the stuffing problem for us was tie-down straps. We got four straps off Amazon and trussed up the bag like a Thanksgiving turkey. It still took two people, but we were able to strap up the sleeping bag, then stuff it into the stuff sack in about half the time and half the cursing. It's still a drag and still a job for two people, just a little faster now.

      The first picture shows the strapped sleeping bag. The second picture shows it inside the…

      best sleeping bag ever

      This sleeping bag is amazing. Fits two adults comfortably, and can squeeze in a small child during colder nights. My three kids (ages 7 and under) can all fit in together and they love it. Keeps everyone toasty warm.

      Wonderful sleeping bag

      I haven't tried out its limits yet, but this bag is just slightly smaller than our queen size bed. Honestly I got it so I would have more room on solo car-camping trips, now I've just got to get out there.

      The only negative I can find is how hard it is to put back into the bag. I wish the bag was a little bit bigger to restuff this fluffy bag back in, then use the compression straps to shrink it back down some.

      Super warm

      Super warm and comfortable. Great for car camping. A bit too heavy to hike with but perfect for a drive up campsite.

      Great and comfortable sleeping bag

      Great bag with fast shipping but couldn’t give 5 stars due to the fact that you can not get the sleeping bag back into the storage bag.

      Prefect 2 person bag, don’t worry about the stuff sack

      I started by jamming the bottom corner of the sleeping bag in the bottom of the stuff sack. Stuff the bag by working in a five point circle, (side, side, side, side, center). Be sure to stuff as much as you can as you go. I had no problem getting the sleeping bag back in the sack but I can see how it can be intimidating, don’t let it prevent you from purchasing this great sleeping bag.

      Sleeping bag 5 star. Stuff sac 1 star.

      This is a comfortable and warm sleeping bag for car camping or even hanging out in the living room. I like that you can separate the two sides and use them as separate blankets. The sleeping bag is hefty, but it will definitely keep you warm.

      My only issue is the stuff sac that is provided. It is a workout trying to get the sleeping bag back in. I know they have videos showing it can be done but it is also done by employees or people who camp often. I relate it to someone who’s never shot a basketball before struggling to make a basket and a basketball player coming along saying it’s easy. All you have to do is this. The stuff sac seems too small for the size of the sleeping bag. After an hour and a half or so of trying I finally got it back in but it took many tries, a few calls to customer service for help, and a lot of sweat. From my understanding there is a larger stuff sac available for purchase but I don’t see why I it didn’t come with it in the first place considering a ton of people are having trouble with the current one.

      In the end, don’t let the 3 star discourage you from getting this sleeping bag. I still recommend it for couples, those with kids, or those who want extra space. I just have to take into consideration the default system as a whole and the default stuff sac isn’t that good.

      Thank you for taking the time to leave such a detailed review! It's great to hear that you're enjoying the comfort and warmth of the sleeping bag. We designed the stuff sack with space-saving in mind. However, we recognize that it may not be the perfect fit for everyone, so offer a larger stuff sack.
