Down almost the best natural insulator for sleeping quilts. Found underneath the tougher external feathers on ducks and geese, it is lightweight, compressible and keep heat incredibly well. 

The quality of down is measured by ‘fill power’ parametr, which measures how many cubic inches one ounce of down will fill.  The higher the fill power the larger the down cluster, which means it will trap more air and warmth, be more comfortable and last for longer.


  • Can be compressed more than synthetic insulation;
  • Low weight;
  • High insulating abilities;
  • Very good warmth to weight ratio.


  • More expensive than other forms of insulation;
  • Loses most of its insulating abilities when wet.

Synthetic insulation

Made from poly fibres, synthetic insulation is used in all ranges of sleeping bags. Synthetic materials can be good insulators, they do not completely replicate the qualities of down.


  • Synthetic insulation is much cheaper than down;
  • Maintains a lot more of its insulating abilities when wet; 
  • Much easier to care for.


  • Less effective at retaining heat when compared to down;
  • Because of its weaker insulating properties, more is needed to maintain similar temperatures to that of down, making it much more if compressed and with a higher weight.

The biggest gifference between sleeper and simple is that simple hasn't got zipper and can't be a blanket and poncho.
