Amazing bagThis sleeping bag is excellent. The amount of down in this bag is almost ridiculous. For the price, I couldn't ask for much more. I shopped around carefully, and checked out a number of bags in person. This one really stood out as the significant bang-for-the-buck sleeping bag. The bag packs down very small, too. The slight extra weight, at 1.45kg (from all the down in the bag) is absolutely worth it. Something I didn't think about was the extra padding underneath makes my sleeping pad a bit more comfortable, and I don't use/need a pillow with this sleeping bag either.

Cozy and warmIt has been a year since I purchased this sleeping bag.
I have gone on several back country hikes in the Rockies, the Great Smoky Mountains, and lived in my tent in the woods of NW Pennsylvania for four months.
This sleeping bag is so so cozy and warm. I really like that your head can be entirely covered. For me, this is the perfect fit. I can turn around easily and still have enough room. My partner tried it and he is has wide shoulders so it was tight for him.
The only thing I do not like much is the weight and the bulk. I thought it was going to be less bulky and a bit lighter. However, for overnight or couple day adventures it is great. For thru hikes I do not suggest it.

Very poor quality/disapointingMy partner and I bought 2 Marmot Never Summer -18 C sleeping bags in
Canada. The bags were very disappointing. I used my marmot sleeping bag
on 2 expeditions and went back to my 15 years old MEC bag which is
still warmer and more breathable. On our first expedition using these
Marmot bags, we were both cold at only 0 Celcius. The down kept
moving to the sides and making clumps, leaving not much insulation above.
The material was also very wet every morning in the Yukon which has pretty dry climate and where our MEC bags worked very well. The bags were very disappointing but Marmot has a good warranty though and took them back, which we really appreciated.

Incredible bag!!I bought this bag just under a year ago and I am obsessed. I’m a freeze baby and use this bag anywhere from 40 degrees down to 0 degrees!!! It is so well built and tough. I’ve ran this bag through the ringer and it is still good as new!!! I love the color and the look of the bag. The pocket is a great feature for your ear plugs or any other little things. The extra warmth around the feet is my DREAM COME TRUE. Thankful for the way you guys perfected this warm bag. I will never use another one!

Warm, light and compactI've had this sleeping bag for two winters now and have always been impressed by its warmth, comfort and compressibility. The warmth to weight ratio is impressive and zips, pockets and toggles are well placed and of good quality. I'm always pleasantly surprised with the size this sleeping bag can be compressed to, given its impressively low comfort temperatures. There is some leakage of down feathers but no more than should be expected. Very happy with this product overall.

Quality Bag!I've been looking for a light weight, compact, zero degree bag for elk hunting above 10K and I think I finally found it. I'm a 5-10 male; 210 pounds with an athletic build. I purchased the regular size and felt that the hip area was a bit tight, so I ordered the long. The toe box seems roomy to me in both bags, shoulders were as expected, and the height of the regular bag was fine for up to 6 foot as described. The long version was roomier in the hips (2" makes a big difference) and will be a better fit for my body type.
This bag is VERY well built. I placed it on my bed beside a competitor's 800 fill bag and this 650 filled bag was twice as high! The zipper is the best I have experienced; no snagging at all. The shell material quality was also impressive; I'm not worried about wet getting in at all. I like that the main zipper can be vented from the bottom. I like that there is a second zipper on the opposite side to fold the top cover down if you don't desire a mummy effect. Great baffles and cinching ability. This bag comes with a stuff sack and a roomy storage bag which it ships in; as a down bag should be. All in all, awesome product.
Writing a review before using the product in the field is not ideal, but I felt the hip width comment might help someone.

warm, comfortable bagin my search for a zero degree down bag, it came down to two options. given that the never summer was almost half the price of the competition, i decided to give it a go.
i'm really glad i did. the bag is very warm, and the quality of the construction is amazing. on top of that, the little features show that the people who designed this bag also use them. from a zip on the side of the neck baffle to allow arms out for reading to a little zip pocket for foot warmers (haven't tried that one out yet... next winter), everything about this bag has been given thought.

So Cozy! Perfect in Grand Tetons & YellowstoneThis is one of the coziest sleeping bags I've ever used. Zipped up all the way, you are completely protected from outside temperatures. I used this in Grand Tetons, where nights were chilly, and in Yellowstone, where it snowed and temperatures below freezing at night. This bag is so puffy/soft, yet packs down so small in its stuff sack. I was able to fit this in my checked-in suitcase with my Tungsten 2P tent, another sleeping bag and 2 inflatable camp pads.
