Contraband Black Label 4010 4inch Nylon Weight Lifting Belt UNPADDED 4INCH NYLON - This means that there is no additional padding such as foam that is used. This allows the belt to provide maximum stability in the core without foam providing a cushion. Comfort is not sacrificed, this belt can easily be worn during an entire workout. QUICK TIGHTEN CLOSURE - A large section of hook-and-loop allows you to quickly tighten or loosen the belt as needed between sets. We suggest adjusting the belt to suit the amount of support you need for each individual set. This will allow your core muscles to stay activated and support is adjustable depending on the weight being used. DURA-LIFE NYLON MESH - A thick nylon mesh is ultra durable and should provide years and years of support without failure. Nylon is known to be much more durable than cotton while being less rigid than leather. A perfect combination for a weight lifting belt. FIVE SIZES AVAILABLE - Contraband 4010 belts come in a variety of sizes from Small to XX-Large. While the belts are adjustable, some users may actually fit into two different sizes. We suggest choosing a size that will fit and is in line with current goals. For example, if you plan on losing weight and fit into two different sizes, we would highly suggest going with the smaller so you have room to grow into it. NO HASSLE RETURNS AND WARRANTY - There is a full purchase price refund within 30 days of your purchase if you are not happy for any reason. After 30 days, there is a 1yr full replacement warranty on this product for any manufacturing defect.
