Space is always of a premium on these mini breaks and to move around checking these guys out, my kit has to be light as well! I was using a Xero 350 sleeping bag. The conditions were pretty warm at night but the bag performed well and i wasn't bathed in sweat.

The full length zip was a bonus. Superlight and compact and just enough space for me in side. Im off tonight to work in the Alps for my first season as an Aspirant Guide. Its still pretty cold high up. I wonder how the bag will perform. I'll keep you posted!
