With Tynor Abs Wrap Neoprene, you can support and compress your abdominal muscles for waistline reduction and use it as a post-operative or post-delivery aid. With a four-way stretch, it consists of three layers of Neoprene foam bonded fabric. Top layer is made of a special fabric with unbroken loops, which provides a flexible closure system for easy application and removal. The inner layer is crafted from high quality nylon fabric, which ensures long-term use, superior aesthetics, and color fastness. Also, Neoprene provides four-way compression and retains body heat at the same time. You will find that this product has a number of features that make it a smart choice. You need to measure the circumference of your waist immediately below your navel based on the size chart.
