The IRON AMERICAN Chalk is the solution for a stronger grip during your workout. IA sports chalk acts as a protective layer to prevent blisters and is less messy than chalk. The chalk is highly repellent to sweat and water to reduce reapplication during training. This is the ideal grip support for all sports such as lifting, gym, climbing, etc. As with all of our products, IRON AMERICAN backs your purchase with 24/7 support and a lifetime warranty, both of which you'll be hard-pressed to find anywhere else!
