      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…

      Warm as burnt toast

      Warm and cozy fluffiness will keep you warm. The warmest synthetic-filled double bag you'll find. Works great for 2 light weight adults. A bit tight for 2 middle weight adults, unless they are really in love.

      Unfortunately, you cant zip up the two halves separately to make 2 singles. Pity, for if they used a single zipper on each half, this would get 5 stars for me. But it's good enough for me to buy another one right now. My wife and I have grown too...prosperous to be classified as middle weights, so we need another bag.

      Great bag. Don’t roll it!

      Very comfortable and warm bag. The large size is awesome.

      When you go to store it, DO NOT roll it up first, just stuff it in the sack — no problem. That’s why it’s called a STUFF SACK!

      Marriage saver

      My wife LOVES it. and with dual zippers, I can throw a leg out to cool off when too warm. She used to be so cold every trip. Now she is warm as toast.

      I can get it back into the bag, but it is not easy.

      GREAT bag, GREAT job Teton!

      I may have bought this from a different website at a bit of a discount last year BUT I've used it a handful of times since and each time I'm either too hot or nice and warm all through the night. Camping in CA and now Oregon. Northern Oregon in February is still pretty cold but we were fine and had had to peel off a layer during the night. I say buy the bag if you're needing extreme warmth. You won't be disappointed unless buying an additional oversized canvas bag for storing causes you alarm cuz you won't be able to stuff the bag back into the original stuff sack without a lot of grief.

      Big on comfort and warmth

      This thing is comically large. You could fit an entire family in here. It's also super flexible - the two sides completely unzip and can become massive blankets. Or, if you're like me and don't mind not having a fully enclosed bag, can be used as two separate sleeping bags. I've used just one half as my own bag on a solo trip and it worked great. The zippers, however, can be finicky and hard to zip at times, but it's not the end of the world. Overall, a great winter sleeping bag for car camping, that can be stretched into the shoulder seasons if you unzip it. Way too overkill for summer, though, but that's not it's purpose.
