THE SIMMS LIFETIME WARRANTY

We don’t believe warranties should be measured by a calendar. We believe they should be measured by whether a product delivered the performance it was designed to provide.

• If you are not completely satisfied with how your Simms product performs, or if it fails because of a defect in materials or workmanship, let us know. We’ll inspect it and determine the right solution—whether that means repairing it, replacing it, or finding another fair way to make it right.

• To review policy details or start a clain, please visit our Warranty & Repair FAQ page.

• The way you care for your gear can impact product longevity - and your warrnaty. Mildew is a wader killer and can be prevented with propper care, for example. Learn more about product care.
