The Marmot Hydrogen Sleeping Bag uses 850+ fill down making it possible to achieve a 30 degree bag that only weighs 1 pound 9 ounces!

It is hard to match Marmot's warmth to weight ratio with certified 850+ fill down. The Hydrogen is the ideal fast, light and warm bag that compresses down to the size of a 1 liter water bottle.

LightForce Ripstop provides a soft, durable and water resistant shell. Velcro-free face muff gives a nice tight closure with no discomfort. Insulated draft tube keeps cold drafts from getting through the full length zipper. Stuff sack and storage bag included.

Regular fits up to 6'. Long fits up to 6' 6".
