The Marmot Quark Sleeping Bag is made from a combination of Hybrid down and synthetic insulation. A great choice for Spring, Summer and Autumn use. 

Marmot says:

You didn’t see this coming: our new ultralight composite Quark 30-degree bag, boasting a body-mapped combo of efficient synthetic insulation and 850-fill-power water-resistant down around the body, head and foot, will make even the burliest of campers swoon.

Some of our favorite features include a fold-down second zipper for ventilation and a curved baffle construction to reduce shifting down. Stuff and storage sack included.

Marmot Down Defender is an insurance policy for your down garments. This specially treated highly water-resistant down offers an extra level of moisture protection for down garments exposed to wet environments. Down Defender helps prevent down from clumping and losing its loft when exposed to water, thereby greatly increasing its ability to keep you warm and comfortable.

  • Stays drier 10 times longer than untreated down
  • Maintains 150% more loft than untreated down in damp conditions
  • Dries 30% faster than untreated down
  • Treatment is PFOA and PFOS free
  • Bluesign approved

Marmot's Quark sleeping bag features down insulation on the top and synthetic insulation on the base, giving you the best of both worlds! Synthetic insulation is far more resistant to compression than down, so you need less of it to keep you warm from the ground. Meanwhile down offers excellent warmth to weight ratio, making it ideal for the top of the sleeping bag where it can expand to trap plenty of warm air to provide insulation. The fact that down is very compressible helps to reduce the packed size of the bag when stuffed into a rucksack.

The only issue I would have is that the bottom of the bag is a light green colour. Don't get me wrong I like the colour green, I just worry that with such a light colour on the base of the bag it will soon show it's wear with dirty marks. But then again if it's kept in a tent and you used on a sleeping mat it would probably be fine. It's a very comfortable bag so I could bring myself to look past that. Marmot also make the Ion Hybrid Down/Synthetic Sleeping Bag which is basically the same bag but warmer with a comfort limit of -8°C, better suited to colder conditions. At least the Ion is dark blue on the bottom rather than light green, a little less noticeable when dirty.
