So, my first time in very cold overnight temperatures. Went to the Lake District which is only about an hour from me, and with the recent snow we've had promised to be beautiful with blue skies and (apparently) low winds. First night was very calm, and I didn't bother with a tarp as no snow was forecast, second night was a little more breezy, but again, didnt bother with the tarp, the air was so dry and no snow forecast. I figured the storm guard on the Clark (NX-250) would be fine. The lowest it got to in the night was 2 degrees fahrenheit. I'll put a list of my gear at the end of this, but I can honestly say I was warm all the time, totally comfortable (and I'm quite a cold sleeper generally)

Was quite happy at midnight (about 8 degrees then), so watched "the godfather" on my ipod touch. great to wake up to silence and gorgeous weather, albeit pretty chilly!
