  • 5yr of use review (spoilers it's great)
Color: Blue Size: Long
Bought this bag in 2019 for some mountaineering and cold weather camping/backpacking. This is a damn good sleeping bag with incredible value for the money. I've slept in temps as low as 5°F or -15°C and was reliably kept warm enough to sleep pretty well. It's very packable and lightweight and also durable. I've had this for 5 years now, it's been soaked in freezing cold water and survived rugged use. This bag still provides superb warmth and lofts up every time. Love the added details like the inner collar and abilities to cinch it around yourself. It's a mummy bag that also doesn't feel super cramped and I'm 6'2 200+. I love this bag and will definitely buy another one to replace if this one ever goes bad. ... show more

  • One of the warmest bags I've used
This bag is by far one of the warmest bags I've ever purchased for backpacking. It has a few drawbacks, but for a TRUE 0F bag it's spot on. Here's what I've done to test it so far. First, I took a backpacking trip in early March (Highs: 40F, Lows: 20F) around Greenleaf State Park in Braggs, OK. It's a 28 mile loop on some rough terrain. It was overcast the entire time, and a light mist seemed to be always falling. None the less, we pushed on and camped the first night within a stones throw of the lake. In hindsight, we should of pushed away from the lake a bit more due to the wind. Within an hour of sunset, the temperature plummeted. We had setup our tents and I had laid out my sleeping bag in my tent to allow it time to fluff up and expand. One thing to note: This bag REALLY puffs up once it's out of the compression sack. Crazy amounts of loft. OK - so after standing by the fire for a few hours the 12 mile day took it's toll and I fumbled off to my tent to try and get some sleep. Normally, I would be crawling into my Sea to Summit Spark II 35F bag, which only has a 1/4 zip (and is a huge pain to get into), and was pleasantly surprised to find that my bag had a full length zipper that would open from the top or bottom. I didn't realize how important this was until later. I crawled in and immediately found the texture of the fabric to be a bit tacky to the touch. I figured it was my cold skin, so I slid down into the bag. At first, it felt like sliding into an ice sickle. After about 30 seconds though, the bag started to warm up and the inner lining of the bag felt much better. Then, almost all of a sudden, I was WAY too hot. I don't mean just a little "let me open the top a little" kind of hot, I mean I almost started sweating within 3-4 minutes of getting into the bag. Holy cow! This is by far the warmest bag I've ever been in. Most of my other bags are 45F down to 35F with very little options to regulate heat other than sticking an arm out or unzipping from the top. Luckily, this bag had a foot zipper that I was able to unzip about 2-3 inches and that regulated the heat perfectly. The next two nights went the same way and I'm hooked. The biggest issue I have is getting out of the bag on cold mornings. I just don't want to. Ha! A+ bag! Highly reccomend. It's a bit on the heavy side, but for the price you can't beat this bag anywhere. ... show more

  • Outstanding Sleeping Bag!
I wanted to fully test the bag in cold weather before I wrote my review. I tested the bag in 19.1 degrees temps and I then measured the inside temp of the bag at my stomach area and it was 80.4 degrees! The inside bag thermometer was not in contact with my body, so the thermometer would not give me false readings. I was only in the bag for 30 minutes when I took the temp readings. This is an impressive bag for the money. I only have one other sleeping bag that will give me those types of results and that is my Military Extreme Cold Weather Sleeping Bag that has 2 inner sleeping bags and a bivy bag. However, the military bag weights about 10 lbs, so it is not practical to carry for backpacking. This down bag weights 3.5 lbs! I ordered the regular size and it is snug on me in the shoulder area, but not too tight to want to upgrade to the "long" model. I am 6'1'' and 215lbs and have an athletic frame. If you are bigger than that, then I would order the bigger version because the sleeping bag will not zip up in the shoulder area. The bag is a great quality product and is designed to be light weight, so don't expect it to look like a military sleeping bag and built like a tank. This bag will be perfect for all my cold weather backpacking trips. ... show more

  • Our Ideal Set Up for Cold Weather
Color: Maroon Size: Regular
Here's the package we bought below. We wanted to get lightweight, compressible gear (for backpacking in mountains for days), that's easy to set up, comfortable, and warm. Ever since we first tried this package out together, we were sold on it, and have used it ever since (January, February, March '21 backpackers this year). And I anticipate using it for a very long time going forward. We used this package on the Appalachian Trail and Rocky Mountains backpacking in single degree weather, and we were as warm being in our own house. No joke. We could not believe how warm and comfortable we were. It would even get hot at times (we had thermal top and bottoms on only) so we had to peek our head out a little to get some cool air. And comfort? So comfortable. We (my 15, 16, 19 yr old boys and I) are never going back to tent camping ever. This is too good. So easy too. No worries about wetness on the ground, rain hitting the tent, packing up a wet tent, sleeping on the hard ground (we even had super killer self-inflating camping pads are that are awesome, but it's still a degree of hardness because you're on DIRT!), mildew worries from tent moisture, etc. etc. The time it takes to set up and take down is incredible. Obviously, you need trees or some other structure to hook onto. But other than that, this is the way to go for us. Best of luck with finding your ideal set up. We found ours.
