Thermarest NeoAir XTherm

This is a fantastic mat if you want lightweight, small packed size, and WARM.  It packs into the size of a 1L water bottle yet has an R-value of 5.7 - enough for winter camping - and is comfortable to boot.  Reflective baffling inside the mattress creates pockets of air that trap heat and keep the mat stable.  You can inflate it by mouth; however to keep moisture to a minimum inside it's a good idea to purchase a Pump Sack, Torrent Pump or Mini Pump.  Comes with stuff sack and repair kit.
