Why We Like The Warmcube Expedition Sleeping Bag
Marmot's Warmcube Expedition Sleeping Bag is tough on the outside and soft on the inside, which is perfect to keep us nice and cozy when we're fending off extreme climates on expeditions. Rated for subzero climates, this bag boasts an internal layer insulated with 800-fill down insulation for a light and lofty feel, and the outer shell is insulated in ElixR Micro synthetic to stay warm even if the bag gets wet. The shell's body is wind- and water-resistant Pertex Quantum fabric, and the Pertex Shield hood and footbox offer waterproof, breathable protection.

Bulky but worth it
[This review was collected as part of a promotion.] Very warm, perfect for winter! Especially if you are easy to get cold like me. My 10yr old son loved it, too.

Excellent bag, but be mindful of the size
[This review was collected as part of a promotion.] While I have not had the chance to put it through its full paces just yet (ordered in high summer, looking forward to winter), the bag itself is very comfortable and well made. The WarmCube technology keeps the down where it is supposed to be and I expect it to keep me warm on the coldest nights. I am happy with my purchase. But keep in mind that just like another reviewer said here it is big and will not comfortably compress down to fit into a standard backpack. The down and construction will not allow for it, it is truly an expedition bag. Be prepared for this contingency and this bag will be your go-to on very cold nights.

High performance bag too large for backpacking
[This review was collected as part of a promotion.] Believe them when they say it’s an “expedition bag”. It is massive. It also comes with a giant stuff sack about 40L in capacity. This said, it is not ideal for backpacking and more geared towards base camp setups and packing in on a sled or mule pack. It would not comfortably fit in my 95L pack even when compressed as much as I could get it. I returned it for the CWM -40 but it was clear that this bag is an extremely high performance bag for the most demanding conditions. The WarmCube design is neat. The Pertex shell seems really good. I would recommend it, but keep in mind that it is an expedition bag, not a bag that will easily be backpackable.
