brand new, never been in the field this is an expedition/artic bag for the coldest, harshest weather there is! this is also the XL version, so more space but with an elasticity to the interior, so it hugs the body to trap more heat. bag weights just less than 4.5 lbs one of the nicest bags out there for true cold weather expeditions,hunting, or anything where your life is at stake of hypothermia. Mountain equipment everest xl sleeping bag comes with storage sack. no stuff sack comparable to Western mountaineering,Feathered friends, Marmot,North face,Therm-a-rest ,etc. when it comes to expedition bags, IMO .
