How to choose
- Insulation. If you want water to stay cold (or hot) for hours, choose an insulated stainless steel bottle. Non insulated plastic bottles are lighter but won't keep temperature.
- Material. Stainless steel is durable and insulated, but heavier. Plastic (Tritan) is lightweight and cheap, but may retain flavors. Glass is heavy and breakable.
- Capacity. Consider your hydration needs. 32 oz is standard for most daily use. Larger sizes (40+ oz) are good for long workouts or hikes, but are heavy when full.
- Lid Type. Wide mouth lids are easier to clean and add ice, but can be harder to drink from. Straw lids allow easier sipping without tilting. Make sure the lid is leak proof.
- Fit and Portability. Check dimensions to ensure it fits in your car cup holder and backpack side pocket. Some large bottles are too wide. Also consider weight when full.
