MYTREX RAKUNO LUMBAR is an ultra-lightweight, slim lumbar support belt designed to make back and core support easier to wear in daily life. Using a next-generation “slide guide” (pulley-style) tightening system, it delivers strong holding power while staying thin and discreet under clothing—comfortable for office work, housework, commuting, and other everyday situations.

A key feature is the W-string structure, with two-level straps that help the belt fit the natural shape of your waist and lower back. You simply pull the strings to adjust tightness smoothly and precisely, so you can choose the level of compression that feels right.

It also offers a 3-way design depending on where you position it: for the waist/abdomen, the lower back, or around the pelvic area, allowing flexible support for different concerns and activities. Breathable mesh material helps reduce stuffiness during longer wear, and the belt can be cleaned easily (machine washable when placed in a laundry net). An extension belt is included to fit a wide range of body sizes (approx. 60–130 cm).
