All Fatboy cooler rotomolded shells (lid and base) are warranted against defects in material and workmanship for 5 years from the original date of receipt. All wear parts (non-rotomolded components) are warranted for a period 90 days from date of purchase (ie. Handles, Drain assembly, T-Latch, etc). Our warranty does not apply to damage caused by negligence, misuse, fire, personal modifications or commercial usage. Accidental or normal wear and tear is not warranted including scratches, dents, chips or discoloration due to usage or sunlight. The rotomolding process will create slight irregularities in every cooler. No two coolers are alike. Minor blemishes, chaffing, scuffs, or rough edges are not covered under warranty and do not qualify for a replacement. Additional warranty exclusions are stated below.

As part of any rotomolded cooler design lid seepage is a normal function to aid cooler lid opening. Coolers are not warranted to be air tight. In most cases your cooler will open easily without having to use the vacuum release button. In some cases when there is an extreme temperature difference the lid may seal so tight that you need to use the vacuum release button to open the cooler. The cooler lid seal merges at the left center of lid. That area where the seal merges may have a slight gap which is normal.

In the unlikely event your cooler is upside down, water seepage will likely occur and does not constitute warranty replacement.

Plastics regularly expand and contract given environmental conditions. Slight lid warping may occur which is not covered under warranty unless performance of the cooler is materially impacted.

Ice retention time is not warranted on any of our rotomolded coolers or backpack coolers. Ice retention is dependent on cooler size, cooler color, cooler use, climate, ice quality, amount of ice, starting food and beverage temperatures, starting cooler temperature, and how often the cooler is opened. To extend ice retention times please read our ice retention tips.
