Yes, for your convenience, the entire tumbler, including the lid and straw, is dishwasher safe.

The tumbler is constructed from durable 18/8 stainless steel and is certified BPA-free, ensuring safety and longevity.

Yes, the tumbler is specifically designed to fit comfortably in most standard car and bike cup holders, making it ideal for on-the-go hydration.

Ensure the lid is securely threaded and tightened completely. Verify that the flip straw is fully snapped down to create a leak-proof seal, as any open points will compromise insulation.

Check that the lid is properly aligned and tightly screwed onto the base. For the straw, make sure it is pushed firmly into its locked, closed position. Inspect the silicone gasket on the lid for any damage or misalignment and adjust if necessary.

Perform a thorough cleaning. Disassemble the lid and straw components and wash them with warm, soapy water, using a brush if needed to reach crevices. For persistent odors, a mixture of baking soda and water can be left to soak inside the tumbler for a few hours before rinsing.

While designed to fit most standard car and bike cup holders, some vehicle models may have unusually small or shaped cup holders. Verify the dimensions of your specific cup holder against the tumbler's base diameter (90 mm / 3.5 inches).
