With a women-specific, tapered rectangle shape and extra insulation at your feet, the Sea to Summit Journey JoII sleeping bag keeps you warm with water-resistant, RDS-certified 650-fill-power down.

  • Features

    • Responsible Down Standard (RDS) ensures the down does not come from animals that have been subject to any unnecessary harm, such as force-feeding or live-plucking
    • Water-repellent, 650-fill-power Ultra-Dry Down™ retains 60% more loft and absorbs 30% less moisture than untreated down; down is also PFC-free and RDS-certified
    • Extra down fill and Thermolite® synthetic fibers in the footbox add warmth where you need it
    • Nylon shell fabric is treated with a durable water repellent (DWR) finish that sheds moisture and helps block wind
    • Women-specific, tapered rectangular shape offers more space than a traditional mummy bag while maintaining thermal efficiency
    • Vertical chest baffles prevent down migration and 3D sidewall baffle maximizes loft right to the edge of the bag to prevent cold spots
    • 2-way #5 YKK® side and foot zippers let you ventilate as needed; oversized zip draft tube keeps out the drafts, while antisnag materials make for smooth zipping
    • 3D hood draws in tight to keep you cozy; neck collar draft tube seals in warmth
    • Internal security pocket keeps nighttime essentials close at hand
    • 20-denier lining fabric is lightweight and soft on your skin
    • Comes with an Ultra-Sil™ compression sack and a nylon storage sack
    • This bag is designed to zip together with another to create a double bag
