Frequently Asked Questions
Will these tumblers fit my car's cup holder?
Most Simple Modern Trek tumblers are designed to fit standard car cup holders. Slim 30 oz models suit tighter or shallow holders better; 40 oz models fit most standard holders but can be bulky in compact cars. Measure your cup holder diameter and depth if unsure.
Are the lids leak-proof enough for the road?
The Trek line uses leak-resistant, four-way threaded straw lids and gaskets to reduce spills. They are secure for normal driving, but like any straw lid, they are not 100% spill-proof under extreme tipping—lockable flip lids or threaded screw tops are safer if you need absolute leak protection.
How do I clean the lid and straw while on the road?
Most lids and straws are dishwasher safe per manufacturer notes; for quick roadside cleaning rinse with hot water and use a straw brush to clear residue. Removing the gasket and allowing parts to air-dry will reduce odors and extend lid life.
