You may find the Helium or Lithuim sleeping bag and others can meet your outdoor needs based on the type of trip taken.
The Marmot models added below will be reviewed seperatly very soon. I've added the links for you to take a look at them and to see what bags will be reviewed and rated.
These are the best models I have chose that will be rated well here. The only factor to be considered is the price and suitability for the type of use a person wants a sleeping bag for.
Marmot sleeping bags are EN tested making standards more accurate for ratings.
