Hi Mark
I carry one of those emergency foil sheets, the type you seem marathon runners wearing at the end of a race. It's very light and I only use it if needed making it more adaptable than carrying a heavier bag. The sheet keeps any drafts off and is surprisingly effective at retaining the heat.
I also carry a pair of cotton socks for wearing at night. No good for wearing in my boots so they never get wet.

So, two years back, the weather was nice. Positively warm all day. I camped at a Bealach at 450m and it was -4 overnight. Going back a bit further we have measured temps overnight of -8. I'm sure others will all have their own experiences. It is not the norm in my experience to be negative numbers, but it tends to be chilly, so you do need to be prepared, or be prepared to have an uncomfortable night. You can always wear your clean clothes in a bag to up the insulation. We will also be doing the reflective blanket trick this year, as those things are very handy to have around. There have been discussions on sleeping cold / hot before as well. The things to bear in mind are tent type or tarp, sleeping bag, mat, clothes and your physiological type. As mentioned at the time, I generally sleep hot, but if I have had a hard day on the hills, for some reason I tend to sleep colder, so I pack accordingly. A good nights sleep is a joy on the crossing.

Colin,
If you are taking an insulated jacket for use at camp, you can use that as an extra layer in your bag if you are cold.

Oh! For gods sack!!! Just take a proper sleeping bag, I'll tel you why!! It can snow usually, it will be bloody cold sometimes at night, and you never know,,,,,
