  • Features

    • Whether you're adding warmth for winter camping, or seeking a standalone solution for warmer weather, this 4-season liner adds safe, controllable and sustainable heat
    • Choose between 2 heating modes: 5V-USB Efficiency mode and 12V Instant Heat mode; liner must be connected to power source to heat (power source is not included)
    • Efficiency mode: Use the included 5V-USB adapter to conserve power and have maximum compatibility with different power sources
    • In Efficiency mode, the HeatZone gradually warms up to 80°F, providing a consistent layer of extra warmth; HeatZone will not feel hot to the touch
    • Instant Heat: Plug the attached 5.5x2.1 mm barrel connector into a power bank with 5.5 mm port (not included) for fast heat in RCS HeatZone
    • Instant Heat mode is also achieved by attaching an optional Vehicle Adapter plug to the 5.5x2.1 mm barrel connector and connecting to a 12V power supply (both not included)
    • Instant Heat mode heats up within 2 min. to approximately 140°F, making it perfect for a quick boost of heat and for use in extreme conditions
    • Lightweight Radiant Carbon Strand (RCS) technology eliminates the bulky wires of traditional heated blanket systems to provide maximum amount of warmth
    • Proprietary 3-layer technology (comfort layer, carbon fiber heat layer and directional layer) provides customizable comfort
    • Comfort Layer made of recycled polyester with soft, cottonlike feel to insulate and comfort
    • Carbon Fiber Heat Layer features conductive stranded carbon seamlessly integrated in the fabric; body-mapped RCS HeatZones™ help raise core temps in the upper body and feet
    • Directional Layer features patent-pending construction points the warmth toward you, not the ground
    • Tapered mummy shape with a gusseted footbox, quarter-length side zipper and drawstring provides easy access and adjustability
    • Waterproof, soft-touch silicone button controls the duration and intensity of the heat with 3 settings (low, medium and high); lasts up to 8 hrs. on low and 1 hr. on high
    • Liner is durable, waterproof and machine washable
    • Integrated zipper pocket stores the included connecting wire, as well as a power bank, your phone or other personal belongings (all not included)
    • Sustainable active warmth works with any compatible 5V-USB or 12V barrel power supply or rechargeable battery (not included); liner must be connected to power source to heat
    • Includes a stuff sack
