Marmot's Ultra Elite 30 Sleeping Bag is filled with ElixR Micro insulation. This insulation features a blend of three different types of fibers to provide optimal warmth, efficient compressibility, and down-like softness and comfort.

Marmot says:

Utilizing ElixR Micro—a synthetic insulation that uses a unique blend of three fibers for maximum warmth, soft feel and high loft—the Ultra Elite 30 is an ultralight ultra-cozy sleeping bag with a host of functional features to keep you snoozing as smoothly under the stars as in your home’s bed. Highly compressible, this bag has an anatomical wrap-around foot box, 3D hood construction, internal stash pocket and all the unique features that makes Marmot sleeping bags so functional and intuitive for your adventure out.

Marmot's new Ultra Elite synthetic fiber sleeping bags are designed and made specifically with weight-optimization in mind – and entirely PFC-free. Weighing just 846 grams (regular) and with a comfort limit of 1°C, the Ultra Elite 30 provides serious competition for down sleeping bags.

It's filled with filled with ElixR Micro insulation which is a unique blend of three different types of fibers to provide optimal warmth, efficient compressibility, and down-like softness and comfort.

Like all Marmot sleeping bags, these bags make no compromises on comfort. The anatomically shaped foot box and 3D Nautilus hood ensure a warm and comfortable night’s sleep. The zippers are equipped with a special anti-snag slider which we personally like as there's nothing worse then getting stuck in your bag when your desperate to get out in the middle of the night.

Overall we think the Ultra Elite sleeping bags are some of the lightest fully featured bags on the market.

Happy camper

Bought this bag for 3 season bivying in the UK Lake District where there is always a lot of moisture in the air and ground is damp even when it's not raining. In those conditions it is worth the weight and bulk penalty over a down bag. I have used it down to 5°C and with head in the cowl it was fine. Has a robust 3/4 length zip with foot box. Happy so far.
