Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.

good entry level bag for backpacking
kallie8 years ago
Pros:
For the price range, this bag is a great choice. It's inexpensive enough, light enough, comes with a compression sack and packs small enough, and is warm enough for most 3 season camping.
I've used it on 2-6 day trips, doing up to 15 miles a day; have been warm in temps in the upper 30s.
Cons:
I never slept well on backpacking trips, and am realizing that the mummy shape is too constricting for me, since I often sleep on my side and there's not a lot of room for different leg positions.
If you're looking to go ultralight, this is a good entry level bag, but you'll probably end up wanting something a little lighter eventually.
=>My all-time favorite bag is the Nemo Aria 35, which for slightly more money is similar in weight, but mind-blowingly more comfortable.

Great Bag

This bag repelled water when needed, kept me warm in the 30's, and stuffs down very well for backpacking. This is a great bag if you use it correctly. Mummy bags work by using your body heat to keep the inside warm. I made the mistake of sleeping with my warm soft slippers along with my wool socks and my feet got cold. The next night I slept with only my wool socks on and my feet stayed warm. I made the mistake of layering my socks on a another trip, and halfway through the night took off my extra pair of socks and my feet warmed up. If you have too many layers on it will be cold. I am a bit shorter and need to pull this bag up around core so my feet can reach the bottom....also key to keeping your feet warm.

Nice Sleeping Bag for Warmer Conditions
9 years ago
I purchased this bag for my wife, primarily for backpacking. The bag was very lightweight and compressible (as compared to the bags we use for car camping), and appeared well-made. Ultimately, though, it was just not warm enough. I figured the 34-degree rating on this bag would be sufficient for any of our adventures (we're unlikely to tackle cold conditions). However, when late March temperatures dipped to the mid-40s overnight, my wife ended up stealing my bag to stay warm (my bag is rated for 20 degrees). So, we ended up returning this one, but will be looking at the Z Flame or Z Torch.

Backpacking-worthy Synthetic Option
6 years ago
I bought this bag for my sister to help get her set up for camping and backpacking. I was surprised at how light and compressible this bag was. Given that it's synthetic, you wouldn't expect it to pack down so well. I'd say it packs down to about the size of a 15-degree down sleeping bag. Another important thing to note is that the Laminina and Lamina degree rating is actually its COMFORT rating, not its lower limit as is often the case. So unlike most 34-degree bags, this one should actually be comfortably usable at 34 degrees!

I went into my local REI to buy a bag. I told the sales rep that I was a fairy novice backpacker looking for something versatile, durable and for moderate temperatures, but one that wouldn't break the bank as a college student. Without hesitation he recommended this bag. Going through the bag, he pointed out some of the features that made it perfect for me. First of all, it is a higher temperature rating, so while it is easy to add liners that would make it more appropriate for even colder weather, it is harder to take away temperature to use in warmer months. Second, it is fully synthetic so that it is undamaged by moisture the way that down would be. The synthetic also makes it cheaper, ultra lightweight, and compact. In fact, the sales rep sold the men's version of the same bag to another young backpacker directly after me. I got to test this bag out for the first time this weekend and it was perfect. It is soft, plushy, comfortable, and lightweight and it compresses so well that it fits in the sleeping bag compartment of my backpack with room to spare. In the evenings it got down in the high 40s and I was perfectly warm and comfortable the entire night. I'm 5'5 and I went with the smaller size and it fit me perfectly, although if I was any taller at all I would go with the longer size. Would definitely recommend!

I used this sleeping bag on a 3 day, 2 night backpacking trip in Mount Rainier National Park. It got very chilli at night but as soon as I slipped into my sleeping bag, within minutes I was warmed up and felt great. Super comfortable and very fitting. Stuffs nicely for the occasion. Had no problems.

Brrrr, not warm enough

Took this out backpacking in June in Oregon- definitely not warm enough. Will return it. Love the weight, compressibility, seams - but will not work for me. Was 40 degrees out and we have a nice REI tent.

It's tricky to find a bag that's altogether..

Lightweight, compressible, warm, AND affordable--but here we are! I am a novice camper and decided on this bag after concluding the specs offered the biggest bang for my buck. Happily enough, the bag kept me warm on a 45° night, but I got very chilly the next night when it dipped to 28°--which to be fair, is below the comfort rating. Additionally, I like that the bag features a small pocket to store my phone and headlamp in and that the purchase includes a mesh stuff sack AND compression sack. Some grievances I had were 1) the comfort rating is a few degrees off, 2) the zipper gave me trouble at times and 3) the bag can't zip all the way to the bottom and open up completely. Overall, I'm satisfied with my purchase and think this is a great option for someone not trying to break the bank on a well-rounded bag.

I bought this sleeping bag in the summer and was finally able to use it for an over night trip into the Grand Canyon (this December). I stuffed the sleeping bag into my osprey pack and when I was gonna go to sleep I took it out of my pack and it was wet. Nothing in my pack leaked or anything. I'm very confused as to why it was wet?

Great Value for the Price

My daughter is just getting into hiking/camping and we were looking for a good starter level sleeping bag. I ordered this for her birthday and was so pleased with the price and the quality of the product. The sleeping bag came quickly and mountain hardware was so easy to use. We'll definitely be shopping here in the future!
