i just threw a new kit together a couple days ago. got this little yellow first aid pouch from walmart for $5 and it had some usable items inside with extra space. added my mag block, mini bic, plastic twine, tinderquick, photon, suunto, signal mirror, rescue howler, and still had room for a mini toothbrush and toothpaste. could cram more in there. my poncho's pretty large. same goes for the heat sheets. I still keep most of my stuff in the $8 proteus ripoff.
