Great sleeping bag, I used it twice so let's see how it goes aging but it's great so far. The one thing I wasn't comfortable with was the inner nylon feel on my skin as I was sleeping shirtless as the sleeping bag was very warm on the last night of summer (~18C) in a rainforest even with the zipper open which by the way gives me confidence that it'll be nicely warm too in autumn and spring. And for Winter, I have a Reactor Thermolite Extreme Liner to go with it if needed. Also, it's very light to carry and packs neatly small. I'm impressed with it and wasn't expecting what I got at this price!

Took this camping over the weekend in early March. 27°F the first night, wore base layers and the only thing cold was my face. If I was slightly smaller in the shoulders and was a back sleeper this bag would have been perfect for me. As a side sleeper it was a bit of a hassle to turn on my side as the bag was a little tight fitting. But the warmth rating is spot on.

I've had many sleeping bags in 50 years of Scouting and this one was fabulous. It was light, compressable and very warm. Zipper was flawless. I paired it with a Reactor liner to provide comfort to even lower temperatures.
I have only used it once thus far for a week of tent camping in summer. It is light easy to carry. I picked for also using backpacking but have not done this yet. It is warm and zips easy. The long was nice for me even at 6' I appreciate the room. Plan on using in Sept and Oct to see if the warmth to weight ration is what they say. I camped a weekend last fall at 30 degrees in a regular bag and it was cold. I read complaints about not being able to fit back in the bag....they must not have experience. If you can roll tight it goes in no problem. Looks good and so far performing. I bought same bag in standard length for the kids.
I'm not a hardcore backpack adventurer or anything, but I do love motorcycle camping, so I was looking for a low pack-volume sleeping bag that wasn't outrageously expensive. I'm also 6'1", 210 lbs. so I needed something roomy enough for me to be comfortable.This bag is super comfortable. It's soft and warm and packs down nice and small for stowing in my bike's luggage. I don't know why the reviewer Adam from Germany said it was impossible to get it back into the stuff sack, because I find it to be quite easy to get it back into the sack. It literally takes me about 60 seconds to roll the bag up and stuff it in the sack.I will say that if the temps drop into the 40s or lower, you're going to need a bit more than this bag can offer, so I'm going to get the liner to ...

But down into the 50s (Fahrenheit), with socks and sweats, I was toasty and slept great.
This sleeping bag weighs more than 2.5 lbs. I used it car-camping in Telluride in July (I'm from the south east US). It was cool enough outside to have a frosted car windshield when we woke up so roughly in the 30's-40's I'd assume. I was just a little chilly in my sweatpants, wool socks, and 2 sweatshirts in my tent with 2 other people. I also bought a 10 liter stuff sack for it- it just barely fits in the stuff sack (in a good way) but it definitely gets pretty small once its in there and strapped tight. Also I'm 5'7 and I was using the full length of the bag, and there's not much side to side wiggle room either- just enough to roll.
Works fantastic as I stretched it capabilities under 30F. Wrapped myself in a insulated blanket and snuggled in this bad boy in 22F weather at night in high altitude. I am personally not a big fan of mummy type sleeping bags as I prefer more room to move around as I am 6’6” (78” in) but it performed well and I have no complaints
I like the feel of this bag, and the construction seems nice. Unlike another reviewer, I did not find it impossible to put back in the "stuff sack." I was, however, expecting it to pack down more. I'm not sure what size that water bottle is in the photo, but it must be some extra large version compared to the standard camelback. That, or someone miss measured with their photoshop. There is no way to compress this sack, and it is 17 in by 9.25 in. Quite a bit larger than I was expecting. Unfortunate for me, as the pack size is important. I hope it is worth it!
Warm as rated, decent zippers. Roomy enough to be comfortable, but without carrying extra weight. HOWEVER, the bag simply cannot be put back into its sack UNDER ANY CIRCUMSTANCES, making the packed volume specification a total lie.Even machine packed by the factory this thing is really difficult to get out of the sack, and it's truly impossible to get back in. The headache this brings packing it back up every night is simply not worth it, so I returned it to the store and will buy a bag whose designers put a bit more thought into the user experience. Massive PITA to save what, 2g of extra sack weight for a sack that fits?
