Shell (outer fabric)
Most of our sleeping bags feature a shell made of ripstop nylon or nylon taffeta lightweight tightly woven. These fabrics are sturdy and breathable, they are quite resistant to weather, while protecting the insulation and preventing it from “escape”. The bags designed for a more “extreme” use are sometimes provided with a laminated Dryloft® of Gore®. This laminate is a little heavier than nylon, but it offers protection against moisture, wind resistance and much better than the latter insulation.
Lining (inner fabric)
According to SIMPLYYELLOWPAGES, lining a sleeping bag has to be comfortable, breathable and durable. Most bags have a light nylon lining, stain resistant and quick drying. Most MEC bags also have a differential section, that is to say that the area of the inner shell is smaller than that of the fabric of the outer shell, which prevents the fabric to roll up and folded.
Synthetic bags are usually manufactured according to the methods of manufacture in offset stitched or partitioning by inclined walls. These methods prevent the formation of cold spots in the bag at the junction of the shell and liner.
Maintenance of a sleeping bag
Always shake, aerate and dry sleeping bag before storing. It will be stored suspended at one end or in a large storage bag outside their carrier bags or compression. You can slide under your bed or open and extended hanging in the closet. The fibers will be less likely to be damaged and will retain all their caloric qualities longer Washing must be done according to manufacturer’s standards. Synthetic insulation bags can be washed in the delicate cycle machine with mild soap. For drying, the dryer can be used at low temperature and by leaving the bag with an object, like a running shoe, so that the insulating material does not compact in one corner or another of the bag. Down bags can generally be washed or machine dried.
