| Material | Keeps cold | Condensation | Care |
|---|---|---|---|
| Single-wall glass | Poor | Yes | Dishwasher-safe, no odor retention |
| Double-wall glass | Fair | Almost none | Fragile; many are hand-wash only |
| Vacuum stainless | Excellent | None | Often not dishwasher-safe; hides the drink |
| Plastic (Tritan etc.) | Poor | Yes | Light and unbreakable, but scratches |
