The front belt and the belt fit system from the sides and back allow for adjustment to the optimal support level. It firmly supports not only forward and backward movements but also 【left and right】 and 【twisting】 motions. Also, you can freely tighten the upper and lower sides depending on how much you pull the left and right sides. 【Posture Correction, Shaping Up Too!】 Corrects posture and reduces the burden on the lower back. The back support belt supports the abdominal muscles to prevent a posture that puts a strain on the lumbar spine, such as "sticking out the stomach." 【Breathable Mesh Material】 The breathable mesh material is used, providing the best breathability and comfortably supporting the entire lower back. The material quickly evaporates sweat. It can be used year-round regardless of the season and provides a comfortable fit. Suitable for labor protection, daily back support, and also for office workers who sit for long periods, carrying work, sports, golf, tennis, sprains, sudden lower back pain, long-distance driving, etc. 【High-Quality Velcro】 High-quality Velcro is used, and the material is durable even after 2000 repeated adhesions. It won't come undone even with vigorous movements such as sports or work, and even beginners can easily put it on. Furthermore, adopting the pulley structure principle, it can be tightened firmly with a light force, so even those with weak strength can easily put it on. 【Unisex】 You can adjust the tightness of the back support belt to your preferred strength while wearing it.
