The Bear Hammock Pillow is double the volume of insulation used compared to our Cub Hammock Pillow, it measures 8"X12" with 5" of loft and with the included stuff sack weighs 5 ounces. Our Hammock Pillows include a 24" shock cord/clip suspension line that clipped to a ridge line in a hammock will tether the pillow in place at the head end of the hammock and keep it from sliding down should the user move around during the night. They work great for ground sleepers (tent users) as well as hammock campers (of course you will be more comfortable in a hammock but that is another story for another day.)
