    Mylar Layers I Zenbivy Sleeping Bag Systems

    Mylar layers

    Mylar is a popular insulation choice for ultralight camp mattresses, but unlike other ultralight mattresses that are crinkly, loud, and provide insufficient warmth, our mattress's mylar layers “float” within to quietly reflect heat and provide R5 warmth for EN/ISO-matched thermal performance.

    Materials I Zenbivy Sleeping Bag Systems

    Laminated fabrics

    Other mattresses use coated fabrics which can break down over time, making them less durable and, therefore, less reliable. We laminate a PU (polyurethane) membrane to our fabrics. This separate membrane does not break down and the welds are stronger, resulting in a more durable and long-lasting mattress.
