Exped Camp & Hike Comfort -10C / +15F Medium Left Zip 7640445450508. The generous cut of the Comfort series at shoulders hips legs and feet increases freedom of movement while maintaining the thermal efficiency of a mummy bag. The sculpted easily adjusted Comfort Hood? insulates the entire head and neck area in colder conditions but opens wide for warmer temperatures. A plush adjustable down-filled draft collar reduces loss of heat due to body movement and the resulting bellows action that can pump heat out of the hood. The collar also adds insulation around the neck where heat loss is particulary common. A zippered arm opening in the seam opposite the main zipper allows both arms free to hold a book play cards or do chores without leaving the bag. BlanketZip EXPED’s zippered foot section opens the foot end of the bag which converts the Comfort into a camp parka for walking around camp in cool weather or with the main zipper opened into a blanket for one or two people warmer conditions. All Exped sleeping bags from our trekking basecamp and expedition series’ can be zipped to each other and to most sleeping bags from other manufacturers. Waterproof stuff sack and mesh storage duffle bag included.
