Sleeping Bag Fill

One of the most useful features of a sleeping bag is its filling. If a sleeping bag has a good type of filling, it can easily keep you warm during the night and save you from having to endure an unpleasant night. This is a sleeping bag’s main strength for keeping your body’s heat well insulated during the night. A good type of sleeping bag filling can do a few very helpful things such as:

• It can allow you to retain a good amount of air pockets.
  
• It can be very lightweight.
  
• They can become pretty compact when they are compressed.
  
• They can expand very quickly.
  
• They can keep you insulated even while you are wet.
  
• They can keep you from getting rashes or allergic reactions.

At this moment, there are roughly two classes of Sleeping Bag fill:

• Down
  

This is still the preferred material for high quality Sleeping Bags. Specifically, Geese down is known for its great insulation characteristics. It scores great on all the qualities expected from a good Sleeping Bag fill. It takes very little space when compressed and it fluffs up fully and easily once unrolled. Down is often graded in 'Fill Power' which is the space it consumes per weight unit. Good down will be at 500" class="related_products_container"-800 cubic inches per ounce. The only problem with down is that is loses most of its insulation qualities when wet and it is hard to wash and dry. Furthermore, good down is very expensive and some people are allergic to it. So you may want to check your allergies before you buy an expensive Down Sleeping Bag. Alaska Heliskiing

• Synthetic Fibers
  

Modern synthetic Sleeping Bag fills try to combine the qualities of down with better insulation qualities when wet and much cheaper prices. There are many of these synthetic Sleeping Bag fillings and some of the most common names are Polarguard, Hollofil, and Micro-loft.

Configuration of Tubes and Baffles

Many Sleeping Bag fillings, particularly down, are pretty much free-flowing. To keep the filling from building up at certain areas and going very thin on others, Sleeping Bags have sealed off compartments that keep the filling from displacing too much. These compartments could be seen as tubes that run across the Sleeping Bag from side to side. Each of these tubes are connected to the other at the tube walls, or baffles. In most Sleeping Bags, the baffles are about 5-6 inches apart. Most synthetic Sleeping Bag fills are not free-flowing and do not need compartments to keep the fill from moving.
