BEDGEAR’s Flow Performance® pillow has a dual-chamber construction featuring soft on one side and firmer on the other. Flow’s fill of React® has a supportive blend of consistently cut materials including silk-like fibers that provides a conforming and pressure relief feel for enhanced comfort. Besides featuring BEDGEAR’s patented Air-X® 100% breathable cover, Flow has a patented air vent design and Air-X mesh sides, creating cross-ventilation for maximum breathability. The Air-X breathable jersey-like cover with metallic-silver-colored piping and slate blue mesh sides provides continuous airflow to let the body naturally regulate its temperature and create an ideal sleep environment. Available in four heights, also called sizes, to meet personal sleep preferences, the lowest height pillow — 0.0 size — includes one air vent and a mesh patch on top and bottom while the other three heights — 1.0, 2.0 and 3.0 sizes — include 10 air vents and mesh on all sides. Only the 0.0 size is not dual-sided; this single-chamber pillow ensures consistent comfort. Flow’s zip-off removable and washable cover creates a clean and healthy sleep environment.
