Big Agnes Air Core Pillow.

At just 2" x 7.5" (packed) and weighing in at just 4.5 oz. this pillow is hardly the size of a soda can.  This pillow doesn't take up much space, but you will be happy you brought it along when you rest your head on this 12" x 16", air-filled dream.  The 2.5" think inflatable pillow is made up of a durable 70D nylon and uses the same I-beam technology used in the Air Core pads.  Either stuff this in the pillow pocket (standard in all Big Agnes sleeping bags), or use it alone in place of the rolled up wad of clothes.

Includes mesh stuff sack
