• Compression and support: This men's sweat vest acts as a lumbar support trainer, increasing calorie burn during exercise and reducing pressure on lumbar muscles, as well as supporting the spine during physical activity. • Improved flexible design: Made with high-quality fabric and durable zippers. The fabric is soft and features two adjustable outer belts that provide a good range of tension and slack. The improved shoulder design makes it easy to put on and take off. • Double belt design advantage: This 2-in-1 waist trainer solves the discomfort caused by different sizes of a single belt on the lower abdomen, allowing for more flexible adjustment of waist belt pressure. • High-quality material: Made of neoprene and nylon, this vest is soft, healthy, and moisture-wicking. Combined with a healthy diet and plenty of water intake, it maximizes results. • Exercise tool for men: This corset training vest can be worn under or over your regular shirts. Ideal for achieving a flat stomach feel, a strong core, and a tight look.
