Fourth Generation Lumbar Support Wide Waist Belt + Heat Pad] After years of research and incorporating customer feedback, we are proud to announce the launch of the medical-certified [Medical Device Notification Number: 13B2X10479302021] F.G.S Lumbar Support. This product features an improved wide waist belt and heat pad to alleviate lower back pain. The heat pad, also known as a hot pack in hospitals, warms the body and relieves discomfort. This warmth is used to improve pain and other conditions. Using the F.G.S waist belt eliminates the need for frequent hospital visits, allowing you to apply it yourself at home and save on costs. Overwhelming Support & 24cm Wide Design] The key points for reducing lower back pain are "firm tightening," "support after wearing," and "ease of application and removal." The F.G.S Lumbar Support has four support stays for strong support, making the wide type that firmly supports the entire lower back reassuring. Furthermore, the 24cm wide design restricts twisting of the lower back while applying wide pressure from the upper back to the lower abdomen, firmly supporting the lumbar spine to the pelvis. The wide design also firmly secures the lower back and prevents slippage. Mesh Material, Excellent Breathability & Double Compression Belt] For long-term use, comfortable wear is essential. Good breathability is crucial for this. The mesh type efficiently releases excess heat, reducing concerns about stuffiness. The double belt provides firm support; the main belt and the auxiliary belt prevent slippage even during vigorous movements and provide firm support. Strong Velcro & Wide Design Based on Human Anatomy] Two durable wide belts, one on the outside and one on the inside, are strongly secured with Velcro. You can tighten them at your preferred position, and the support belt allows you to adjust the tightness for a secure fit. It stays in place comfortably for long periods, naturally maintaining the correct posture. The wide design is based on human anatomy, distributing the load on the lower back, firmly enveloping and supporting it, reducing wearing stress, and promoting a well-calculated, correct posture.
