PHYSIKAY Waist Trainer is designed for both men and women with adaptation to most skin types crafted with the best materials for skin sensitivity. The trainer features a double layer support design made from durable, stretchable, and breathable material that firmly and completely covers your waist comfortably, while providing you moderate core support during exercises. With the 3 layers integrated Neoprene fabric design, the trainer increases core body temperature and promotes blood circulation to aid your workout thereby making you sweat more, burn more calories and lose weight faster for up to 3hrs. Along with a healthy diet, it not only can be worn during exercises, but can also be worn on top of thin clothes for up to 6 hrs daily for body shaping support. PHYSIKAY Waist Trainer's simple top layer Velcro closure enables you to pull and adjust the trainer to a comfortable state bringing to life an instant waistline curve.  Most importantly, it is easy to maintain for long lasting use.
