Have been camping now for 4 years and still I cannot guarantee that I will be warm at night.
This bank holiday weekend we had 4 nights away. The cloudy ones were fine. I was wearing: long sleeved thermal top, thermal bottoms, slipper socks, fleecy PJ top.
The clear nights were chilly. I wore all of the above and added a hoody sweatshirt (with the hood up!), another pair of socks and a pair of tracksuit bottoms. And I was still not all that comfortable! My sleeping bag is quite a good one - Mummy style.
DH says I'm a wimp. My 2 DS's sleep in just PJ's and socks and are sweaty!! Am I just a cold blooded wuss?
