Best Selling Down Sleeping Bags

"Down" is a pure, natural, thermal-insulation product grown by birds in cold climates enabling them to survive severe weather conditions. The insulation properties of down enjoyed by birds living in these conditions has clear benefits when applied to sleeping bag fill, and the performance benefit of down fill over synthetic is significant.

For a given temperature rating, a down bag will be both lighter in weight, and compress down to a smaller size when packed. The advantages are clear when you are carrying your own kit on a trek or expedition where weight needs to be kept to a minimum and pack volume is limited.

Best Selling Synthetic Sleeping Bags

The most noticeable difference with synthetic fill sleeping bags is the price! However, it is well documented that synthetic bags provide less thermal insulation for a given weight and volume of fill, so if price, weight and pack size are not an issue then synthetic bags start to become more of a consideration.

There is another consideration, and that's when things start to get wet. Synthetic bags have a distinct performance advantage over down when wet, maintaining a higher thermal efficiency with a reduced tendency of the fill to 'clump' together. Synthetic fill also dries more quickly than down, with moisture transport away from the inside typically 20% faster than down.

Although synthetic fill does not compress as easily as down, this does have the effect of providing synthetic bags with higher insulation potential under compression, so the base of the sleeping is more efficient at retaining heat.
