No more midnight drawcord fumblingsmooth, flat upper cord and hard, round lower cord make hood adjustments easy. Hood closure system stays closed without the use of rip-and-stick and also keeps the drawstring and zipper away from your face. Spacious 11-baffle footbox allows down to loft fully; footbox is reinforced to handle extra abuse of boot liners and water bottle. Down-filled draft collar increases warmth; hidden pocket in down-filled draft tube keep small items such as lip balm or your watch warm and accessible. Zipper guards prevent zipper snags; locking, full-length zippers keep bag from opening in the night. Comes with nylon stuff sack and a storage bag. I always slept in the sleeping bag fully clothed and it was never too warm in that environment. I would recommend the -40 sleeping bag to anyone who sleeps cold or wants the ultimate cold weather bag. I was never too hot and the Pertex membrane ensured that the tent frost did not penetrate the exterior shell. I recommend this long (6’6) sleeping bag for the additional storage of boot liners and water bottles required in extreme cold environments. Price includes original Storage Sack and Stuff Sack. The bag was washed with Nikwax Down Wash but still looks and smells new. The item “Marmot CWM EQ -40 Long Sleeping Bag Right Zip” is in sale since Saturday, February 20, 2016.
