What Is a Silicone Foldable Cup?

A silicone foldable cup is a reusable drinking vessel made from food-grade silicone that folds flat when empty. Originally popular among hikers and campers as a space-saving alternative to rigid water bottles, it has gone mainstream as the ultimate eco-friendly, travel-friendly everyday cup.

• Rigid Plastic: Does not fold, limited temperature range, $5–$15

Best Uses for Silicone Foldable Cups

Care Instructions

Most silicone foldable cups are dishwasher safe (top rack recommended). For deep cleaning, use baking soda paste or white vinegar. With proper care, a quality silicone cup will last 5–10 years.
