Overpriced, decent bag

Bought this on sale for about $500, I've spent 50+ nights in this bag. It's not worth the price tag. It says 0 degrees, but sleeps more like a 20-30 degree bag, the lack of a draft collar is RIDICULUS for a bag of this price. If you're a side sleeper I would highly recommend something else. It's durable enough, it does lose a few feathers through the thin shell. The interior stash pocket is too small for anything more than a small light. The zippers function well, it's decently warm for it's weight. Again, this bag desperately needs a draft collar.

About Marmot Lithium Sleeping Bag

Primary use: Backpacking

By Kathy L.

Really great and warm sleeping bag that packs down well!

Ultralight fabric, high-quality down, and a minimalist design come together in the Lithium 0 Degree Sleeping Bag. Suitable for mountaineers and backpackers adventuring in temps down to 0 Degree F, its lofty 800-fill-power-down insulation and water-resistant Down Defender treatment stays warm and dry. After an epic day on the mountain, give your feet a rest in the roomy wrap-around footbox. Smooth, curved baffles help keep the fill in place, while the nautilus multi-baffle hood with a drawcord, snagless insulated draft tube, and full-length two-way zipper with a zip-guard slider limit heat loss. If the interior gets too warm, use the fold-down secondary zipper to get some air. Tuck small items into the internal stash pocket.
