I got very cold and shivery a few weeks ago in Wasdale. We'd jog / walked over from Honister to help with a BG and conditions were good, but I hadn't really got a warm enough layer to put on while we were waiting for the contender. I ended up warming up in a car, with tea and a sleeping bag over my legs. A Primaloft jacket would have been a big help (I was carrying full Gore-tex cover, but there's no real warmth in them)
