T&C Surf Custom Bottles Warranty: Online Order Number is mandatory for the warranty to be valid through our online shop.  NO EXCEPTIONS. This warranty does not cover regular wear and tear such as dents, scratches, powder coat chips from the bottle being dropped, damaged, etc.  Your Hydro Flask, Yeti, or Stanley bottle can be exchanged if it sweats, rattles or no longer insulates as long as there are no dents on it (pictures will need to be provided).  You may also exchange your bottle if there is discoloration inside the bottle or rough welds along the rim of the bottle (pictures will need to be provided).  Please note that T&C Surf can only replace the bottle for the exact same size, color, and design.  Unfortunately, we cannot cover the costs of customized engraving, stickers, or any other applications.  This warranty is valid at T&C Surf for 1 year after purchase.
