Rated 1 out of 5 by from Cinch cord does not work. Would not buy this bag. Was excited when I received this bag due to positive reviews I read. Got it out of the shipping box, and tried the cinch cord to close the hood around my face. It hardly cinched the hood at all. Went to a local store and tried the cinch cord on a couple of other Helium MemBrain's and they had the same problem. Salespersons could not provide an explanation other than it should cinch almost all the way closed, but the ones tested hardly closed at all. Called Marmot and the customer service rep got a regular Helium and cinched it almost completely closed. She did not have a Helium MemBrain to test. Returned the bag I purchased. Considering purchasing a regular Helium 15F bag.

Rated 2 out of 5 by from Did anyone at Marmot test this? I tested this bag in fall 2012. At 2#6.4oz it was a bit heavier than advertised. Though it seemed to add considerable bulk, the waterproof breathable membrane was a strong selling point with me. Pluses: differently shaped drawcords; two hang loops at the foot. Minuses: no pad loops; no pocket; and it is practically impossible to cinch the hood and collar. The drawcords seem to stick – maybe the “MemBrain” on the inside of the little nylon tunnels creates too much friction? If so, it should be easy for Marmot to fix, after which the bag would have a lot to recommend it. This apparent design flaw was a deal-breaker for me. Without that issue, I would probably have given it four out of five.

Rated 5 out of 5 by from Need a light, warm, moisture-resistent bag? This one ain't just the shiznit; it's the shiznizizit! If you're looking at this bag, it's because you're intrigued by shell fabric, right? Right. So, let's cut right to the chase: the MemBrain fabric WORKS. Now, it won't keep you dry in a torrential downpour (duh!), but it does deal handily with the saturating dew of the Pacific Northwest's Hoh Rainforest; many a morning I've awoke after sleeping under the stars to find my bag completely covered with dew, yet the insulation was perfectly dry and lofted. Brilliant!,,,,BOTTOM LINE: if you're facing heavy dew, or even light drizzle, but you don't want to pack a shelter, or obscure your view of the brilliant night sky, suck it up, pay the extra money and the three-ounce penalty, and BUY THIS BAG!

Rated 5 out of 5 by from This is an awesome bag, best of both worlds 850 fill down + water proof shell on EQ. This bag packs up about the size of a can of coffee and does not seem to weigh anything. It fluffs up really big when released from it's cage. It attacks cold like an angry lion. Purchased the bag for an early summer mountainering trip to Wyoming and damp/cold conditions in Smoky Mountains. It has never let me down. Replacing a Gore-Tex Moonestone bag with this one, because the Gore-Tex makes crackling noises when you roll over that are really loud and wakes everybody in camp up. The newer form of marmot g-tex on this is very quiet,windproof/waterproof. Can't go wrong with a Marmot bag!

Rated 5 out of 5 by from It's warm, light, compact, & it's going with me everywhere I go! I've had this bag a few months now & only have great things to say about it. It's kept me plenty warm on several mountaineering trips in the Sierra's & the Cascades. I only use one pad (NeoAir) and temps have been down near zero at times... I was still warm (I don't usually have problems in the cold though)! The bag stays dry = bonus. And my favorite part to this bag is the amount of space inside. I'm 6'4", weigh 210 lbs and have no problem staying comfy all night long in this bag (I bought the long). I am very happy with this sleeping bag.

Rated 5 out of 5 by from Amazing bag, top quality, but at a price. This is by far the nicest sleeping bag I've ever had the privilege of lying in. The 850 goose down feels snug and warm yet can also be compressed unlike any synthetic bag. The hood is a perfect fit to block out nasty breezes while allowing the occupant to breathe freely. Clearly, this is a well designed product. I'm happy I spent the extra money for this quality bag, I plan to use it for the rest of my life as long as i continue exploring.

Rated 5 out of 5 by from It doesn't get any better than this!! So soft. So comfortable. So warm (but not ridiculously warm). So light. So small packing. So-co and lime is delicious. So nice looking and blue. So good to not have to worry about a little bit of moisture affecting your beautiful down bag. So the nicest bag I have ever owned. So........... buy it and you wont regret it. So good!

Rated 5 out of 5 by from Talk about quality! Admittedly this is my first down sleeping bag, but I wanted to start off right. First campout I stayed toasty warm, dry, and comfortable. Bumped the tent and had some condensation rain down on me and the water just rolled off the bag. Especially like how small it compresses into the included stuff sack. Very impressed!
