      Really warm

      Really good sleeping bag especially for two people but like everybody else on the reviews it’s a pain to pack it in the bag if anybody has any good ideas on how you’re supposed to pack it or is there a video that customer service can send us or make it would be really appreciated on how to pack it correctly Otherwise really great product.

      So comfortable!

      Couldn't wait to get to a campground so the day it arrived we pitched a tent in the backyard. Temps reached the high 30s and we could not have asked for it to be any warmer in this bag. Its fill is deep adding a ton to it's comfort. It's huge, so we intend to only use it when we are parked near by, I guess we could hire a sherpa to carry it for us backpacking, lol! Seriously looking for our first real adventure with it, possibly snow, now that we have gear for every time of the year, Thank you Teton!

      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…

      Great sleeping bag for the family

      Haven't camped with it yet., but my wife likes the bag, and the kids love it too. It keeps you warm when it is chilly, and it is comfortable too.

      Best sleeping bag ever!!

      This sleeping bag is extremely well made and so comfortable! My hubby and I aren’t super slim and we fit very comfortably and cozy :)

      The customer service people are fantastic! They called me back within a couple hours and helped me answer a question regarding price matching and took care of me! :) definitely recommend this company to others and will use them in the future!!

      WARM!

      I love this sleeping bag. I slept in 17 degree weather and I was nice and toasty. It’s perfect for tent camping, car camping and trailer camping. It’s nice to snuggle next to your partner. Only downside is the size. It’s HUGE and a pain to get in the bag. I did master it rather quickly as watched the YouTube video multiple times before even attempting to put it back in the sack. I opted for buying a second compression sack and storing the top and bottom of the sleeping bag in their own sack. I just unzip it all and put it together when I get to my destination. This has been a huge difference for me since I have a hurt shoulder.

      Awesome

      The double sleeping bag is perfect for two or can be seperated into two bags. Great quality and super durable. Perfect for winter camping.

      My sleeping bag.

      I love it! It's nice and warm and it looks beautiful. The only problem is that it's too slippery.
