Review Image by Jonathan Jonathan
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

    • Quieter than many bags, good loft, short means short.
Bought this bag in short for my 6 year old, figuring it'll last a long time. She slept in it three nights in a row, so that's a win. I've slept in it once to try it out. I'm 5'10" and it's too short for me. Probably okay for those 5'6" and under. It's cozy, and the nylon isn't super noisy like some bags. I don't like the zipper, which stops before the feet - good for warmth, bad for venting if you get too hot. The zipper also is super fiddly to restart when you accidentally unzip it all the way in the dark while half asleep. That's the negative bits. We got the 0 degree bag - haven't tried it below freezing yet (it's summer), but it seems well insulated and snugs up over the shoulders. The hood portion was a no go for me (too warm and I am too tall), but it should be great for my kid for the next 9 years or so. Super affordable and seems reasonably well made. Only thing I really don't like is the zipper, but it's not my bag, and the kid doesn't know any different! ... 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

    • Kozy Warm Bag for cold weather
This is very very good down bag for the $$ , We went scout snow cave camping. Temps were in low teens at 2000 ft elevation near Mt Hood. My Son slept in this bag, inside of a US Military Gortex Bivy with a Klymit Airpad with Mylar reflective surface Sandwiched Between bag and Bivy. We replaced the original Military Black Sleeping bag with the Hyke & Byke Snowmass 0. He slept on the Snow and ice directly with this gear. He was warm and comfortable thru the night. The bag warmed up quickly and the Snoring Commenced. as discussed else wheres the zipper is a weak point. The Nylon that is used for Lining the Zipper path is to light weight and 1/2" to narrow. This allows the zipper to Pull the bag nylon into the zipper as it is being pulled closed, thus jamming, The material is fairly tough but will fail over time and cause a feather leak. The learned technique it to hold your index finger as a guide and separator for the bag material while zipping it up. This keeps the soft light material out of the zipper path a heavier wider material to line the Zipper path would remedy this trouble point. Other wise excellent warmth and air trapping comfort. Guards Red Color is terrific . ... show more
