With "garment-style" construction, the innovative Sierra Designs Mobile Mummy 800F 2-Season sleeping bag includes armholes, a jacket-style hood and a stowable footbox so you can literally wear it around camp. Featuring 800 fill duck DriDown water-resistant down insulation and strong nylon ripstop shell fabric for waterproof protection, the Mobile Mummy 800F 2-Season is a high-quality, extremely durable and versatile bag for warmer weather camping.
Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel, and despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one inherent weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet, but the DriDown featured in the Mobile Mummy 800F 2-Season bag performs differently. Employing a unique, innovative polymer application, DriDown actually creates a hydrophobic finish on each individual plume of down. This treatment results in insulation that stays dry up to 10 times longer and dries 33% faster, should it become wet, than untreated down bags.
Unlike traditional mummy-style sleeping bags, which can be restrictive for campers who tend to change position frequently throughout the night or who don’t sleep stick-straight on their backs, the Mobile Mummy bag is designed to move with you whether you’re fast asleep or up and about making breakfast in camp. The garment-style design through the shoulders allows the bag to rest there instead of your head, so if you sit up with the hood on, the Mobile Mummy sits up too without applying uncomfortable pressure to your head and neck. And that hood has no cords or toggles, but just fits snug around your face like the hood on your favorite insulated jacket. The armports are zipperless and also free of any other uncomfortable hardware like toggles or hook and loop closures. They, like the hood, central zipper, draft collar, draft tube and draft curtains are all reinforced with additional interior down baffling to prevent cold air drafts. The centrally placed 58" zipper is dual sliding, which allows you to vent the bag or put your feet out to stand up and move about – the footbox can be tucked up with toggles to stay off the ground when you’re walking!
The Sierra Designs Mobile Mummy 800F 2-Season sleeping bag is available in Regular (fits up to 6' 0") and Long (fits up to 6' 6") sizes. A stuff sack and storage sack are included.
