What Is Included
The product is described as a two-pack of bottles. The description does not specify other included items, so check the selected configuration if accessories matter to your choice.
How It Works
To drink, gently bite the soft part of the mouthpiece and press the bottle. The description says that pressing harder increases water flow. The bottles are also designed to hold minimal air to reduce water sloshing.
Care, Cleaning and Storage
Rinse the bottles thoroughly before use. To address an unwanted taste, the directions say to add water and 1/2 teaspoon of baking soda, shake well and rinse. The flexible bottles can be folded or tucked into a pocket, as described.
Before You Decide
Confirm whether 8.5 oz is the capacity of each bottle, check fit with your intended storage or hydration gear, and make sure the two-bottle quantity suits your needs.
