Neck Pillow prv Gray 【Ergonomic Design for Optimal Neck Angle】 This neck pillow conforms to the principles of human engineering, gently supporting the head, neck, and shoulders, aligning with the natural curve of the cervical spine. The design supports the neck and back of the head, reducing strain on the shoulders, spine, and neck, and relieving fatigue through comfortable sleep. It's suitable for various uses, such as long-haul flights overseas, Shinkansen travel, sleeping in cars, and napping in the office. 【Easy to Use】 Unlike conventional air holes, the large air hole allows inflation with just 2-3 breaths, even for women. Unlike other products that use a pump to inflate, there's no worry of pump damage, and the absence of a pump or exhaust port around the neck ensures comfortable sleep in any position. Air adjustment is also possible, allowing you to use it as a lumbar support with your preferred firmness. 【Soft-Touch Velour Fabric】 The latest version of the neck pillow has been upgraded from nylon fabric to velour fabric, providing even more comfortable sleep. It's harmless, odorless, and leaves no marks on the face or neck, making it ideal for long periods of sleep. By removing the cover, it can also be used as a floating pillow in a pool or bathtub. The cover is removable and washable, allowing you to maintain a clean state and prevent odors and bacteria from growing in the pillow. 【Comes with a Portable, Ultra-Light Storage Bag】 An ultra-light storage bag is included, perfect for travel and short trips. After storage, it's ultra-compact and lightweight, fitting in the palm of your hand, making it easy to carry by hanging it on your bag or storing it in a small space. You'll no longer have to carry a large pillow.
