【Cabeau Evolution Cool】 Used once. I'm selling it because I no longer have the opportunity to use it. It's in a clean condition with no stains, and as described below, it was breathable and comfortable without getting stuffy. * Breathability and a pleasant cooling sensation: The breathable mesh-covered memory foam sides and back vents provide a continuous cooling effect. * Size-adjustable pivot loops: Using the two front pivot loops, you can tighten or extend the pillow to fit the thickness of your neck. * Unique two-layer structure: Whether your head tilts left or right, or forward, the slightly higher layer firmly holds your neck 360°, reducing neck fatigue. * Removable and washable cover material: The moisture-wicking fibers have excellent functionality, absorbing sweat and releasing moisture to the outside of the fibers, and it's easy to wash. * Easy storage in a carrying case: Cabeau's deluxe travel case compresses the pillow to half its size and allows for easy storage and attachment to a bag, making it convenient to carry.
