It's Cold...But Not Inside! I Love It!
This HiZYNICE Cold Weather Sleeping Bag is less of a sleeping bag and more of a portable heated apartment with a zipper. I bought it for cold-weather camping, and I’m fairly certain this thing could survive an Arctic expedition, a blizzard, or possibly the next Ice Age. First of all — the XXL size is AMAZING. Finally, a sleeping bag clearly designed by people who understand that adults enjoy things like breathing, turning over, and not sleeping wrapped like a refrigerated burrito. There’s actually room to move around comfortably without performing advanced yoga maneuvers at 2 AM. The 100% cotton flannel interior is ridiculously soft and cozy. The moment you crawl inside, your brain immediately starts negotiating reasons to never leave. It feels less like camping and more like being hugged by a very warm bear that pays your electric bill. And the warmth? Unreal. I used this during cold weather and at one point had to unzip it slightly because I was beginning to suspect I had accidentally entered another climate zone. This thing traps heat so well I’m convinced nearby campers were slowly migrating toward my tent like penguins during a snowstorm. The build quality is excellent too. Heavy-duty zippers, durable materials, and thick insulation all make it feel extremely well-made and built for serious outdoor use. Despite being oversized and super warm, it still rolls up surprisingly well for transport and storage. Whether you’re camping, hunting, working outdoors, RV traveling, or simply preparing for winter survival against suspiciously aggressive weather forecasts, this sleeping bag is fantastic. Highly recommend for anyone who enjoys warmth, comfort, personal space, and surviving cold temperatures without becoming a human popsicle. Absolute beast of a sleeping bag!

Amazing Bag and Fantastic Customer Service!
Quality: Very good quality and super soft and comfortable to sleep in or on top of as a mat. Warm, sleek, nice to look at. Not an ugly bag at all. Warmth: This bag is incredibly warm and even being on top your body heat is stored very well and traps easily. This is great for colder conditions and will keep you toasty! 🔥 Zipper: The side zipper is a bidirectional zipper: one zipper pull is on the top and can be unzipped from top to bottom for shoulder ventilation, and the other zipper pull is on the bottom and can be unzipped from bottom to top for leg ventilation. Storage and Carrying: Super easy to pack up and pull out when needed being a moderate weight bag. For how warm it is it’s not super heavy! The storage bag has a handle like grip and the strap goes over the top so it won’t fall out accidentally on you. The bag has plenty of room as well so even if your tucking isn’t tight you’ll fit it right back inside with ease! Customer Service: My bad had a mild issue with the zippers having an issue on the side of the bag and I may have just got a dud, but the brand customer service helped me solve all my issues. They explained the bag design and functions and really ensured they undertook the problem in order to solve it. I got a full refund and they were super respectful and informative. Great Buy!

Great Purchase!
I bought this for my husband's turkey hunting trip last year and it hasn't disappointed. He said it was the warmest sleeping bag he's ever owned. The inside material is super soft and it's large enough to get comfortable and cozy. Its not super heavy but it does have some weight to it, and the quality is wonderful. Its not too bulky and rolls back up like a dream. Great value for the price!

A Perfect Fit for the Big and Tall, Ultimate Comfort and Warmth
As someone who stands at 6 foot 3 inches and weighs 350 pounds, finding a sleeping bag that can comfortably fit my frame has been nothing short of a challenge. Regular XL sleeping bags never seem to zip up around me. However, the HiZYNICE 0 Degree Sleeping Bag with its XXL sizing has proven to be a delightful exception. Here’s why: Pros: Spacious Design: The XXL size is truly extra-extra-large. This sleeping bag is not only long but also generously roomy, fitting me comfortably even with my rounder middle. Quality Material: Made with 100% cotton flannel, the bag feels soft against the skin and ensures cozy warmth, even at 0 degrees. It's perfect for chilly nights outdoors. Ease of Use: Unlike other sleeping bags that struggle to zip around larger individuals, this one zips up with ease. No more struggling with closures that don't fit! Warm and Comfortable: The insulation and fabric work together to create a sleeping environment that keeps you warm without overheating. Versatility: Suitable for a range of outdoor activities, from camping to road trips. It's a go-to sleeping bag that you can rely on. Cons: Bulkiness: Due to its larger size and quality materials, it might be slightly bulkier to pack. But this is a minor trade-off for the comfort and warmth it provides. Conclusion: The HiZYNICE 0 Degree Sleeping Bag is an absolute must-have for those who are big and tall and have struggled to find a sleeping bag that fits. Not only does it offer ample space and length, but it also delivers on warmth and comfort. The quality of the fabric and construction make it a worthy investment for anyone seeking a top-notch sleeping experience while embracing the great outdoors. I can't recommend it enough – it has quickly become a favorite part of my camping gear, and I'm sure you'll love it too!

Cozy, Versatile Flannel Sleeping Bag for All Seasons
I am a keen camper, and I thought this flannel sleeping bag would be perfect for me, and I have to add it has become one of my favorite items when camping. The thing that makes this sleeping bag most appealing is that it is comfortable and versatile. The 100% cotton flannel lining is very comfortable to the skin making it easy for you to have a comfortable night sleep while out in the wilderness. It is comfortable at 30°F, has a low limit at 15°F and an extreme at 0°F so it is ideal for three season use. Measuring 90 x 39 inches it is large enough to accommodate tall campers up to 6’7” or anyone who desires more space inside the tent. The anti-snag zippers are used to operate the pocket from inside or from outside and from top to bottom and can be used for the purpose of easy access and for having ventilation. I find it useful to be able to connect two bags to get a double sleeping bag for two people or a couple with a child. It is also easy to wash making it easy to keep clean between the trips. However, there are two possible negative aspects which are worth to be discussed. It is unclear how much the flannel sleeping bag weighs, but these bags are generally heavier than synthetic or down ones, which can be an issue for thru-hikers. Also, it is probably larger and heavier and hence easier to pack than other more specialized sleeping bags.

Finally a sleeping bag that keeps me warm AND doesn't make me feel trapped
I recently purchased the HiZYNICE 0 Degree Sleeping Bag, and I must say that I'm thoroughly impressed with its performance. As someone who is big and tall, I was looking for a sleeping bag that would provide me with enough room to move around in my sleep, and this sleeping bag does not disappoint. The XXL size is perfect for my needs, and I don't feel cramped or restricted in any way. The 100% cotton flannel lining is also a great feature of this sleeping bag. It's soft and comfortable against my skin, and it keeps me warm by trapping in heat. The durable polyester outer shell is also a plus, as it provides me with protection from the elements. The HiZYNICE 0 Degree Sleeping Bag is designed to keep you warm even in temperatures as low as 0 degrees Fahrenheit, and I can confirm that it lives up to this claim. I recently took this sleeping bag on a camping trip in colder weather, and I was impressed with how warm and cozy it kept me throughout the night. One thing to keep in mind is that the sleeping bag can be a bit heavy and bulky to carry around, but I find that this is a small price to pay for the comfort and warmth that it provides. The compression sack that comes with the sleeping bag also makes it easy to pack up and take with you on your next adventure. Overall, I highly recommend the HiZYNICE 0 Degree Sleeping Bag to anyone who is looking for a warm and comfortable sleeping bag, especially if you're big and tall like me. It's a great investment for anyone who enjoys camping or outdoor adventures in colder weather.

Warm, soft, roomy, great price, easy to pack.
Ive had a backpackers, below freezing sleeping bag for like 10+ years and while that has a purpose, I had the realization that I wanted a big, old school flannel kind of sleeping bag. This sleeping bag totally fulfilled everything I wanted. I had forgotten that you can use sleeping bags for comfort and not just to function (like not getting frozen). I'm like 6ft, 240 pound guy and it had enough room for me to move around, rotate and get comfortable. The flannel lining is nice. I will admit its not the softest but I think after a few uses it'll get soft. It just needs to get broken in a little bit. I'm also surprised at how light it is for the comfort and warmth it brings. Protip: if you're buying it for the first time, I would highly suggest rolling it out a few days before you take it camping and let it breath. It will come vacuum sealed so the sleeping bag will initially be a lot smaller. Let the fabric get fully expanded and then roll it back in.

Big, warm and soft!
I am a plus size woman, and this sleeping bag gave me room to switch positions inside the bag, without having the bag roll with me. It kept me warm and cosy!
