Simple Modern Trek Tumbler

No, this lid is specifically engineered to fit only the adult Trek Collection vessels. It will not fit other Simple Modern drinkware lines, so please verify your specific model before purchasing.

The lid features a unique quarter-turn threading design that allows you to screw it onto your tumbler in four different positions. This lets you align the flip lid opening to your preferred side, making it equally comfortable for left-handed or right-handed drinkers.

Yes, the lid is designed to be leak-proof when the flip closure is fully engaged. It provides a secure seal that prevents spills during daily use, though you should ensure the flip mechanism is snapped shut completely.

Yes, this lid is top-rack dishwasher safe. Its durable, BPA-free construction is designed to withstand standard dishwasher cycles without warping or degrading.

Yes, the lid features double-walled construction that adds an extra layer of insulation. While the tumbler itself does the heavy lifting, this lid helps maintain your beverage's temperature for longer periods compared to a standard, non-insulated lid.
