Thinking of try this. Zlite style mat which has 14 sections: - Cut 4 sections off and use it as an external backpad like on GG rucksacks (so it would be 2 sections wide and 2 thick) held in position by shockcord. - Use the remaining 10 sections as a sleeping pad. Anyone use this style of backpad, is it comfortable and preferable to an internal folded pad or burrito style? If i still wanted to use all sections to sleep on - any suggestions on keeping the 10+4 sections connected together so they dont slide apart through the night?
