As with all purchasing decisions, all based on your personal preferences and travel considerations.
My recommendations are:
- Stainless Steel/Insulated Bottle: Yeti Rambler 18 oz Bottle ($29.99)
- Glass: Contigo Purity Glass Bottle ($16.99)
- Collapsible: Nomader Water Bottle ($23.95)
- Plastic: Nalgene Tritan 32-ounce BPA-Free Bottle ($10.99)
My personal "go-to" is the Yeti Rambler 18oz Bottle.
