Launching early 2026

The Synthetic Light Bed You’ve Been Waiting For

Introducing the Light Bed with PrimaLoft® synthetic insulation. Lightweight, warm, and ultra-soft, it’s ideal for campers who can’t—or simply don’t want to—use down. 

Now available in a new 25°F build for colder nights, and our updated 40°F Synthetic build is lighter than ever before.

PrimaLoft® Insulation

The industry leader in synthetic performance and technology, PrimaLoft® insulation is thoughtfully engineered from ultra-fine fibers, delivering lightweight, thermally-efficient performance.

Performance

  • Warm

    Ultra-fine fibers trap body heat efficiently for consistent comfort.

  • Lightweight

    High warmth-to-weight ratio keeps the weight of your pack down, without sacrifice.

  • Soft

    Fine fibers create a down-like, ultra-soft feel.

  • Durable

    Designed to withstand years of adventure and repeated washing.

Sustainability

  • Recycled Materials

    Made with 100% recycled materials, sourced primarily from plastic water bottles.

  • Reduced Emissions

    PrimaLoft’s Unique manufacturing process cuts carbon emissions by more than 50%.

  • Landfill & Ocean Impact

    PrimaLoft has diverted nearly 1 billion plastic bottles from landfills and marine environments over the last decade.

  • Enabling Circularity

    Built with recyclability in mind for a sustainable end-of-life solution.

New! Synthetic Light Sheet

The final piece to complete your synthetic Light Bed. For the first time, those who prefer synthetic can enjoy the same full "mummy-bag warmth" as down users. The Light Sheet Synthetic features an insulated hood rated to 25°F.

Two Footbox Styles, Two Temperature Ratings

    Fast Footbox™

    Available in 25°F Synthetic only

    Unlike sewn footboxes that restrict your movement and do not vent, Zenbivy’s patent-pending Fast Footbox™ uses a single clip that allows it to expand for more space or narrow for more warmth.
