When used/carried properly all ICEMULE Coolers are designed to not leak. However, most of our coolers employ a roll-top closure which can leak when turned upside down. While our roll-top ensures easy access and is excellent at keeping contents insulated and ice cold, there will be moderate leakage if the cooler is tipped over for an extended period of time (gravity is a pretty powerful force). If you know your cooler is going to be tipped over for a long period of time, we recommend using ice packs instead of ice.
The ICEMULE Traveler has a watertight zipper and it will never leak as long as the zipper is closed all the way, and locked in place.
If your cooler is leaking and you are doing everything right, reach out to Customer Support and we’ll resolve your issue.
