Set of 2 [Pelvic Belt] This pelvic support belt solves problems such as pelvic misalignment after childbirth, lower back pain from long hours of desk work, lower back pain during daily chores and childcare, difficulty bending over, and discomfort from maintaining the same posture while driving! This pelvic supporter uses two belts to firmly secure the lower back, and the stretchable material allows for easy tightening, supporting the burden on the pelvis. [Dual-Layer Belt for Double Compression] The pelvic belt has a two-layer belt structure: an inner belt (main belt) and an outer belt (two strong auxiliary belts on each side). This allows you to firmly secure your lower back while adjusting the tightness to your liking. The main belt stabilizes the pelvis, and the strong auxiliary belts can be adjusted to your preferred level of tightness, providing a comfortable fit that won't slip even during strenuous activities like sports. [Velcro for Easy On and Off] The waist belt is easy to put on and take off with Velcro, so anyone can use it without any hassle, and it's stress-free when going to the restroom or changing clothes. The thin design is discreet under everyday clothing, providing support without being noticeable at work, during childcare, or while exercising. It's compact and lightweight, so you can easily carry it with you when traveling or going out, and use it whenever you need it. [Made of Natural Rubber with Air Holes, Flexible and Breathable] The waist supporter uses natural rubber and, despite its thinness, has moderate elasticity that doesn't interfere with daily activities even when worn. In addition, it has air holes, making it breathable even when worn for long periods during sports or work, and comfortable to use throughout the year. [Precautions for Use] Prolonged use (e.g., overnight) may cause circulatory problems, so please use with caution. This product uses natural rubber, which has a characteristic odor. The odor will fade with use, but please be aware of this beforehand.
