Showcasing 50 years of experience in making down bags, the Helium 400 down sleeping bag by Mountain Equipment provides all-around performance for climbers and backpackers.

Insulated with high-loft, premium 725-fill-power duck down for warmth, light weight and compressibility
Downproof and wind-resistant, the densely woven synthetic shell is light, compressible and tough; silky soft lining is also downproof and highly breathable
Durable Water Repellent finish on shell causes water to bead up and roll off
Ground-level side seams allow top layer to fully wrap around body and keeps draft tube in place, further helping prevent cold air from seeping through the zipper
Slant box wall baffle construction uses slanted walls for stability and thermal efficiency; construction keeps down from migrating, eliminating cold spots
4-baffle trapezoid footbox is wide in toe area and narrow at the heels for comfort that does not compromise warmth
Protecting the head and neck, the hood features 5 baffles and an anatomic fit to provide warmth and low weight
Alpine Fit features a semi-tapered mummy profile with a tapered lower leg section to maximize warmth and minimize weight without restrictiveness
Single antisnag draft tube (along the 3/4 length zipper) and semi-floating neck collar drapes comfortably, blocking the escape of heat and sealing out drafts
Mountain Equipment Helium 400 down sleeping bag comes with a lightweight stuff sack and mesh storage bag

Imported.

Comments about Mountain Equipment Helium 400 Sleeping Bag:

I have used this sleeping bag once in Northern MN where the temp dropped to 27 degrees F. I stayed comfortable with this bag wearing heavy long underwear bottoms, light top, and wool socks.

Pros:
Neck collar: I really enjoyed this feature as it prevented cold air from getting in when I would roll over. I also get claustrophobic with a hood tight around my face; I can cinch the neck collar down and leave the hood looser which gives more breathing space.
Down on all sides: I'm a side/stomach sleeper, and I could roll around in this bag and still be warm. Other light weight bags have less insulation on the bottom, which would work great if you can stay on your back.
Compressible: I purchased this bag because it was the most compressible for the price. It's listed as 7 x 11, which I imagine is the stuff sack size. I was able to compress it in the bottom of my 48 L pack to even smaller than these dimensions. I don't believe there is a significantly more compressible bag regardless of how much you spend.
Light weight: There are lighter bags out there, but most of them are significantly more expensive.
Space: I am 72" and 175#, and I fit well in the regular (listed at 72") size with a few inches to spare lengthwise. I also had extra room widthwise. Be careful when comparing this bag to the Xero (another series of bags of the same brand) as the "long" Xero is the same size as the "regular" Helium.
Warm: It is comfortable at its listed rating. You could probably even go lower while wearing long underwear.

Cons:
Minimal accessory features: This bag doesn't have full length zipper or a pocket.
Not in stores: I had to purchase online as it was not stocked in any of the MN stores, and they were not expecting to stock it any time soon.

Summary:
One of the most compressible and lightweight bags for the price with an accurate temperature rating.

Service and delivery comments:

It arrived in good condition before the expected delivery date.
