Marmot Helium Sleeping Bag Series

The award winning Marmot Helium and Helium MemBrain sleeping bags are some of the lightest 15 degree sleeping bags on the market today. Because of their overall weight, Backpacker Magazine awarded Marmot’s ultralight bags their 2008 Editor’s Choice Gold award. But just because the Helium and Helium MemBrain bags are lightweight doesn’t mean they are lacking in warmth and features. Let’s look at some of them below.

Marmot Helium


Marmot Helium 850 Fill

The Marmot Helium sleeping bags are insulated with certified 850+ fill power goose down, which is the best weight to warmth down on the market today. The down is certified at an independent facility in Salt Lake City, Utah before being used in any of Marmot’s sleeping bags. This down exhibits excellent loft, and one of the coolest things to witness is to take your bag out of its compression sack and watch it expand like a balloon.

There are several features to these bags that are designed to keep you warm and comfortable through cold nights. An insulated draft tube keeps warmth from exiting through your zipper. A Natuilus 6-baffle hood prevents heat loss through the opening around your face. The outer material is made of a durable yet flexible material that prevents wear and tear but allows your baffles to expand to their maximum loft.

The Helium MemBrain model features a waterproof Pertex Shield shell and Pertex Microlight lining fabric. This is a great feature, as we all know the problems that can occur when down sleeping bags get wet. Even though this sleeping bag is waterproof, it is also quite breathable, allowing for an all around comfortable sleeping experience.

The weights of the Helium and Helium MemBrain sleeping bags are as follows (regular – long)

  • Helium 15 Degree Down: 1 pound 15 ounces – 2 pounds 6 ounces
  • Helium MemBrain 15 Degree Down: 2 pounds 5 ounces – 2 pounds 9 ounces
