Our PU (polyurethane) pillow bladder is lighter than fabric bladders, squishier, and transfer weight less severely, resulting in less bounce. More importantly, the bladder is designed to be used for what it’s good for: a base to simply add height and support at minimal weight. Pair the air bladder with a pillowcase and down pillow topper to create a Zenbivy SoftTop™ Pillow, or ditch the down pillow topper and sub in your puffy jacket to create an ultralight version.

*Pillowcase and down pillow topper sold separately.
