Quick Answer
If your S'well Tumbler is sweating, it's likely due to a damaged vacuum seal or extreme temperature differences. Check the seal and avoid overfilling with ice.
Why Condensation Happens
S'well Tumblers use Therma-S'well® Technology with triple-layered, vacuum-insulated construction designed to keep beverages colder or hotter longer. Normally, this prevents condensation on the exterior. If you see moisture, the vacuum seal may be compromised, or the temperature difference between your drink and the air is too extreme for the insulation to handle.
What to Check First
Before assuming a defect, check if the tumbler is overfilled with ice or very cold liquid. Overfilling can cause the lid to not seal properly, leading to condensation around the rim. Also, ensure the tumbler is clean and dry before use.
Diagnosis & Fix Steps
- Symptom: You see moisture or water droplets on the outside of your S'well Tumbler, especially near the base or lid.
- Likely Cause: A damaged vacuum seal (from a drop or impact) or extreme temperature difference between the drink and ambient air. Overfilling with ice can also cause condensation around the lid. If the tumbler was dropped, the seal may be broken and cannot be repaired.
- Corrective Action: 1. Empty the tumbler and let it reach room temperature. 2. Fill with hot water, seal, and let sit for 5 minutes. If the exterior gets hot, the vacuum is compromised. 3. If no heat transfer, test with ice water for 10 minutes. If condensation reappears, the seal is likely broken. 4. Clean the lid and silicone gasket thoroughly, ensuring it's dry before reassembling. If the vacuum seal is broken, the tumbler cannot be fixed. Contact S'well support for warranty options.
- Stop or Choose Another Option: If the vacuum seal is confirmed broken, stop using the tumbler for hot or cold beverages. Consider replacing it. For condensation around the lid only, try reducing ice and ensuring the lid is fully closed. A broken seal means reduced insulation performance; the tumbler may still be used for room-temperature drinks.
