Section Hiker has posted warnings for those people trying to assess the potential warmth of their sleeping bags. Key points are:
- The winter sleeping bag temperature ratings are assigned by manufacturers and fall outside the new EN13537 sleeping bag standards. The temperature ratings on most winter sleeping bags are probably 10 degrees too warm.
- Women need winter sleeping bags that are 5 to 10 degrees warmer than men.
- Most winter sleeping bag temperature ratings assume that you are wearing long underwear including socks, sleeping on a sleeping pad or pads with a high combined R-value, and you are in a tent or bivy sack.
