  • Our Lightest, Most Premium Bed

    With soft feather-light 10D Pertex® Quantum fabrics, premium fill options (900+, 950+, PrimaLoft® Gold), and patented comfort features that are inherently light, it turns out ultralight can be ultra-comfortable.

    Starting at just 3 ounces, the uninsulated Fast Sheet is the lightest way to block all drafts and eliminate all constriction.

  • Ultralight & Uncommonly Supportive

    The offset air cells create a diagonal baffle pattern that causes the mattress to twist against your body’s natural fold lines rather than collapse into them like horizontal and vertical baffles, resulting in a more supportive mattress.

  • Minimalist Pillow

    The 2-piece Minimalist Pillow includes a removable pillowcase and an adjustable air bladder, letting you customize both height and firmness. Layer your down jacket or other soft clothing on top of the air bladder for ultralight comfort! 

    *Down jacket not included

  • Simplify Your Packing Process

    Simplify your packing process. The Zenbivy Pack Liner is a fully waterproof, easy-to-compress dry sack that holds all your sleep gear in one compact layer at the base of your pack—saving time, maximizing space, and eliminating frustration.
