Altos 20F Synthetic

My friend recommended this bag to me in 2018. I love the weight, reliability, comfort, and ease of packing with the compress pack. I took mine to hike Mt. Fuji in 2018, where it got completely soaked for 4 hours as I hiked down the moutain and typhoon Jebi caught me off guard. It dried out well and went on many more adventures and counting. It's small enough to comfortably use for sleeping in a compact car on long road trips, random camping trips, survive the freezing nights of the Mojave desert, and can be spread out roughly on top of other blankets as an extra precaution against the cold. In 30°F weather, it gets too hot within an hour. I always have to open the zipper and let it breathe more. It was comfortable to as low as 20°F weather with no wind-chill when fully zipped. The thickness is nice and adds extra cushioning that helps me sleep or camp out in the most random places that I've ended up in. Bang for buck, this is the best sleeping bag I've ever got at this price point and one of my most reliable. The zipper and build quality is durable and beefy, while staying light weight. The comfort is amazing. I wish I could recommend this sleeping bag more and give it a 10 out of 5. My family members and friends loved it too and some have been buying it after trying mine.

Wow oh wow! I am blown away!! I received this bag yesterday and wanted to write a review of my first impression. While the bag was in its carrying sack, it was very lightweight and compact! The bright orange was very appealing and it was easy to fit in/out of the sack. I immediately hopped in and it was very soft and cozy with plenty of wiggle room to turn on my side or roll over. I still had plenty of leg room at the bottom of the bag as well. Once zipped up, I felt just like a mummy! I’ve not yet tested it outside in the cold weather, but I immediately felt warmer once I hopped in. I’m excited to test this out and will post an update once I’ve done so! I am a long distance hiker and plan on using this bag for “The Pacific Crest Trail.” Your Company has an amazing reputation and the bag is very affordable in comparison to other brands.

This sleeping bag is comfortable enough but does not provide the amount of warmth I was hoping for. I'll start with the negative being that warmth seeps out of this bag. Despite my best attempts at closing in the opening, without anything else to slow the temperature drop, it's going to get uncomfortable. If you move in your sleep, you'll get colder quicker. The good news is it'll keep you alive until the sun, movement, and coffee in the morning can reheat you. It is imperative that you put boiling water in a Nalgene bottle to stuff in this bag for overnight so you can get a decent night's rest. I've also had to put on toe warmers in my camp booties to keep my feet from being the reason I wake up in the night. The positive is that this is a great price for the weather rating. I look forward to using it for weather over 32F as we transition into the late spring/summer months. It has great compression and is perfectly lightweight. I stuff it in my backpack without the stuff sack as the buckles are too bulky and with a few good shoves from the top, I manage to fit a plethora of other kit in my pack. It will remain a staple in my backpack for the fall and spring seasons.

Going into it, I didn't expect this bag to be comfortable at 0f. But for the price, if it was comfortable at 32f(0c), I'd be happy. I took it out on a 40f night and camped by a river so it was a bit damp. It did great, I was plenty warm. I was only wearing sweatpants and a cotton shirt so I'm confident with the proper base layers, it would be fine at 32f. Just understand that, like most bags, the official rating is extreme. That said, $100 for a lightweight sleeping bag that's comfortable at 32f is really good value.

Great bag that used upon receiving. Had gone down to bellow 40. Kept me warm and like the zipper woks well, just tuck the inner liner. Packs well for a motorcycle trip. Highly recommend

Ok so I haven't yet taken it camping. I have used it in my living room and was very warm and comfortable. Easy to put in the stuff pack and had room for my travel pillow which I accidentally put in the pack. Glad I took the chance on this bag. My husband who is 6' -210lb thought it was to tight on his shoulders so he is opting for the one that is 2' wider and a bit longer from the same company.

I've slept in this in 30 degree and 65 degree weather and was completely comfortable both times. The cinch feature around the head and neck liner really keep in the warmth. I'm 6'0, 200 lbs and I feel like it could use one more inch at the head but it wasn't terrible. It is a bit slippery on my inflatable sleeping pad, but otherwise it's compact, lightweight, dries fairly quickly, and well worth the money. Don't hesitate to buy this bag.

I did a lot of research before buying this sleeping bag and I was kind of skeptical as I’ve never heard of this brand before, I guess I saw just their backpack but after being frustrated with over priced rei and other brands, I decided to give it a try. Suprise! it is absolutely amazing! First time I didn’t feel cold (it gets pretty cold in Northern California) Super comfy and reasonable size! I just wish the storage bag was more practical to use. I probably burned 100cal trying to pack it back to its bag but other than that I’m 100% satisfied with my purchase. Even tho carrying bag is eh… Im still giving 5 star! I also got another one for my wife and we are super happy with both of them, highly recommend!

First and foremost, this is an excellent sleeping bag for the price. It's a very warm bag (perhaps too warm for all but the coldest nights) but it's also not excessively heavy or large. I purchased the bright orange bag rated for 0F (-18C) and the bag itself comes in at only 1295g (2.85lbs) and with the included compression bag the whole things is 1455g (3.2lbs). It packs up reasonably small for a 0F bag, but it's still a significant volume even when compressed. Pros: - Extremely warm bag - Packs up to a respectable size given the insulation value - Very light given the insulation value - Material feels soft and comfy, if not a little cheap - Very good neck baffle, and mummy top drawstring - Zippers are well baffled - Shape is snug but comfortable - Color is pretty cool Cons: - Zippers feel cheap. I wish they used a better quality zipper and charged an extra $10 - The bag is warmer and larger than most people will ever need, but it's their lightest bag - Zipper frequently snags inner baffle when closing - Drawstrings feel a bit cheap I find Teton's ratings and weights to be incredibly confusing, and there are several nearly identical looking products spanning the $99 up to $300 price points all with pretty non-sensical weights listed, with significant discrepancies between their website and Amazon. This matters a lot for those backpacking and looking for a lightweight sleeping bag, so having unreliable numbers there isn't great. Finally, I wish Teton would make a truly ultralight and compact 30-40F bag using the same general construction as their 0F bag, but with less insulation. There is a lack of good options for simple fall camping where a bag like this one is really too warm, and as a result, larger and heavier than needed. If they could make a bag like that at this price point, I would buy it in a heartbeat.

primeras usadas y primeras impresiones 1ra noche temp de 5° con casa normal de verano , el sleeping fue muy muy caliente... termine durmiendo con tines y boxer no aguante el aire caliente y baje poco el cierre y abriendo la puerta de la casa 2do uso, temp de 0° con llovizna, casa de 3 estaciones se portó de maravilla .. vestimenta ligera nuevamente. fue comoda la temperatura interior... solo note humedad externa por condensacion ,creo que mientras mas frio el exterior el sleeping te ayuda a generar mas calor o aprovechar tu calor a lo que por combinacion de temperaturas se genera condensacion... lo senti mas en la zona de piernas... seguire usandolo y actualizare info...tamaño perfecto para 183cm Actualizacion.. usado en el izta con casa 3 estaciones , ropa pijama, temp -4° una chulada de sleeping para mantener el calor. debajo use un pad de yoga y colchon inflable.

Long term review: I am writing this review 5 years after my original purchase, over which time I have used this for 2-4 weeks per year. The sleeping bag has been fantastic. It is still going strong without any major issues. The zips have held up well and the synthetic down remains warm as ever. I have no complaints about this bag and it has seen me through camping and hiking in all conditions. It's very warm, which is great if you run cold, but is sometimes too hot for summer camping in Australia (often I will use it unzipped or half on me for warmer nights). It's long enough for my height of 6 ft and I enjoy the cozy mummy shape, although I've had friends who find the tight leg space uncomfortable.

My husband and I bough these for interior camping in Algonquin Park. We just got back from a very chilly and wet long weekend and these sleeping bags were the highlight. After reading many reviews about various sleeping bags we went with the Teton Sports Altos 0F. They are super light weight and come in their own compression sac and packed down to less than half of 1 of our normal sleeping bags. I was worried about the warmth with the material being so light but we were warm each night. I usually wear full base layer with hood and socks while sleeping but wanted to give the bag a good test so slept in underwear and sports bra. Temps were probably less than 10 C overnight and I was sweating and had to open the bag. Hoping the fabric holds up to multiple trips but thus far we are very happy with the purchase!!!

Sleeping bag looks great but the cover bag is just too bulky and a bit heavy, not that good design, so inconvenient for putting it in the backpack!!
