Just come back from the HUBB-UK and as the weather was cooler a few days before hand its was time for a sleeping re think i packed the Snugpak elite 4 and a sleeping bag liner. The liner was used to cover the mat open the bag up to the feet area which i slip over the bottom of the mat. Plenty of room to move about and toasty warm this set up was topped off with a proper full size pillow which made for a goodnight sleeps. Also a few beer helped as well.
