At Klean Kanteen, Inc. (“Klean Kanteen”) our goal is to reduce single-use items, plain and simple.  So we make products guaranteed to hold up to whatever life throws at them.  Because we are proud of our products and our quality controls, we back our products with a Strong as Steel Lifetime Limited Warranty against manufacturing defects for as long as the original purchaser owns the product, starting from the date of purchase or delivery (if later than the date of purchase) when the product is purchased from us or our authorized sellers in the United States, unless otherwise prohibited by law.  Klean Kanteen will repair or replace a product that is covered by this warranty, or will refund the purchase price of the product in the event Klean Kanteen is unable to provide a replacement and repair is not commercially practicable or cannot be timely made.  For replacements under this warranty, your Klean Kanteen product will be replaced by the same size and color if still available.  If a like product is not still available, it will be replaced with one of similar size and color and will not be of lesser value.

Please note that because we are unable to control the quality of our products sold by unauthorized sellers, unless otherwise prohibited by law, our warranty is not available for products purchased from unauthorized sellers, including unauthorized internet sites.  Klean Kanteen reserves the right to reject warranty claims for products purchased from unauthorized sellers.  The warranty is limited to the original, end-user purchaser in the United States.  For international warranty claims, please work through the distributor from whom you purchased the product.  A list of our distributors is available here.

The warranty does not cover:  damage from improper use or misuse; damage caused by cleaning, disassembly, alterations, or modifications; damage caused by, or resulting from, normal wear and tear, abuse, fire or Acts of God.
