Down Sleeping Bag or Synthetic Sleeping Bag?

June 22, 2017

When picking a sleeping bag for your outdoor trips, one of the most major factor for your ultimate purchase is: Down sleeping bag or synthetic sleeping bag insulation system? Among most of the variables to consider when you selecting a sleeping bag, including the temperature you are going to or mostly camp in and the price or your budget, compressibility and weight of the sleeping bag, the performance of the bag is largely decided by the filling material, fabrics and design elements of other layer like its shell and liner playing an important secondary role.


The purpose of sleeping bag insulation is to slow the transfer of heat from your body to the cold air in the environment around you by trapping it in a narrow layer of air next to you. Air is a poor heat conductor but nice insulator. The loftier the thermal layer, the higher the warmth-to-weight ratio of that product. Both down and synthetic filling can provide these valuable room for warm air to settle, and they all have its pros and cons. Compared with each other, down insulation share these features, light and compressible, durable-lasting well over 10 years, fantastic weight to warmth ratio, more expansive, loses ability to insulate entirely when wet. Synthetic insulation holds these qualities, insulates when wet, dries quicker, non- allergenic, not compress as well as down, poorer weight-to-warmth ratio(heavier than down), less expensive.


At the end of a long day of hiking or backpacking, tired and fed already, we love the felling of crawling into a cocoon of soft warmth provided by a quality down sleeping bag. Down is spectacularly nice for ultralight minimalist or bike packer who measure success in margins of grams and cutting volume. We’ll often opt for down on short weekend excursions where the risk is less among major people. Consider that a well cared-for quality down bag will last decades. And for critical missions or wet weather camping, long trips or extended expeditions deep into the wild without bailout options, synthetic is your best choice.
