Sleeping Bags — Insulation

Sleeping Bag Insulation 

Down and synthetic are the two choices for sleeping bag insulation.

Down provides the most warmth and is great for staying warm in cold weather camping. It is very durable and lightweight. But it will take longer to dry than synthetic, so if you expect situations where it will get wet then opt for synthetic. Down is also more expensive. With proper care and cleaning it will last a lifetime.

The synthetic sleeping bags are easy to care for.  They are resistant to moisture, but if they do get wet will dry quickly, just put it out in the sun for a while.  Most can be machine washed.  These bags are heavier and bulkier than the down bag.  Loft describes the fluffiness of your bag. The more fluffed it is the softer it will be!  The fluffiness also affects how warm you will be in the bag.  The fluffed up bag creates hundreds of pockets of dead air space within the insulation.  As your body heat warms the inside of the bag these air pockets will insulate and slow the heat loss.

*************************

A large range of options are available for any budget, as you have choices weight, durability and price. Many choices of synthetic are available today.  Some of the more popular ones are Polarguard®, Primaloft®, Thinsulate®, and Thermolite®.  Other names are also on the market, all having the same basic characteristics of synthetic fill.
