One piece of kit I would highly recommend, not to stray too far from the point, is something called a Zarsky sack. I hope that is the right spelling. It is an emergency shelter, the group sits inside on the edges and it makes a dome shape. QUOTE]
Alchemist, the spelling is correct. The shelter is also known as a bothy, or kisoo. The size varies from a 2man shelter right upto one suitable for 8 people. Like you I have used these a fair bit, and have found them great, for taking short breaks on wet hill sides to get a quick warm to boost morale, taking lunch breaks. And the odd casualty on the hill.
Just make sure when you you take a break through choice, to get out of the wind, and party member with wind stays out. Can get very warm quickly in these shelters, and stuffy!!
Check the link below to give you an idea of the designof the kit if your curious.
