Frequently Asked Questions
Are stainless double-wall tumblers better at keeping drinks cold than plastic?
Yes. Vacuum-insulated stainless tumblers generally outperform plastic double-wall cups for long-term temperature retention. Stainless construction and vacuum insulation reduce heat transfer, so iced drinks and hot beverages stay at stable temperatures longer.
Do these Simple Modern Trek tumblers fit car cupholders?
Yes. The Trek 40 oz is designed to be cupholder friendly — reviewers frequently note it fits standard vehicle cupholders despite the 40 oz capacity, thanks to its tapered base.
How do I clean the straw lid and prevent odor or residue?
Remove the straw and lid components for hand-scrubbing or place them on the top-rack of the dishwasher if the manufacturer recommends it. Use a small straw brush and periodically soak lid parts in warm, soapy water or a vinegar/baking soda solution to remove trapped residue and odors.
