【Size Confirmation】To ensure the best fit, please refer to the size chart below and use a soft measuring tape to measure your neck circumference and neck height. Neck circumference for 3"and 3.5" neck height: Small: 11" - 13 1/2", Medium: 13 1/2"-16 1/2", Large: 16 1/2"-19 1/2". If you are between 2 sizes, please choose the larger size. 【More Options】This neck brace stands apart from VELPEAU's Comfort, Dual-purpose, and Enhanced versions by offering stronger and more stable support. Note: The size range for this version varies from other models, and for the same neck circumference, two neck height options are available. Please carefully measure both your neck circumference and neck height before purchasing, and refer to the size chart to select the appropriate size. 【Perfect Curve Design】 Ergonomically designed, the brace features a "V" shape around the chin and gradually decreases in thickness, offering stability without stiffness. The curved sides provide additional neck support. With a hook-and-loop fastening, the tightness can be easily adjusted for comfort. Suitable for both men and women, it's ideal for sleeping on flights, watching TV, working on a computer, or reading. 【Multi-layer Composite】 This neck brace is crafted from high-elastic sponges, foam, and PP plastic, providing soft yet firm support for the jaw and neck while limiting mobility to relieve pain and pressure on the spine. It helps realign and stabilize vertebrae, reducing headaches caused by cervical strains and sprains. Ideal for post-operative rehabilitation and injury support. 【High Quality】 Made with top-grade, environmentally friendly materials, this neck support is free from toxins and odors, ensuring it's gentle on the skin. The latex-free foam is lightweight, breathable, and promotes air circulation, keeping your neck cool and dry even during prolonged use. 【Adjustable Neck Collar】 Compact and lightweight, the neck brace wraps easily around the neck and secures with an adjustable hook and loop fastener, allowing for a precise, customized fit. 【Care Instructions】 After washing, avoid wringing out the brace. Instead, squeeze out excess water by hand or with a towel, then let it air dry in a cool, shaded area. Do not iron, machine dry, or expose to direct sunlight.
