With its "cross-net taping structure," this product firmly supports your lower back! This thin lower back supporter with taping function is also designed for comfort! ● The "cross-net taping structure" provides broad support for the lower back. It specifically restricts excessive lower back movements, such as "forward and backward motions" and "twisting," which put a strain on the lower back. ● The fabric uses a thin, breathable, and highly elastic stretch material (Lycra fiber). The structure fits the body easily, providing a more comfortable feel, and can be used by both men and women. ● Back extension (arching the back) suppression function. The cross-net sewn into the fabric provides broad support for the lower back. It restricts excessive movement by supporting the lower back from the lumbar vertebrae to the pelvis. ● Core support function. The three-dimensional fit shape, based on ergonomics, supports proper posture by sandwiching the lower abdomen and lower back, reducing the burden on the lower back. ● Thin design for comfortable wear. By using a thin, breathable fabric, it is less likely to get stuffy and can be worn with minimal discomfort. ● Available sizes: Regular M (65cm-85cm), Large L size... around the navel: 80-100cm ★ Relaxed large size / LL size... around the navel: 95-115cm 【How to use】 (1) Hold the product with the "top" tag on the right inner side, and pull with both hands to make the left and right sides the same length.
