Wide Mouth Water Bottle
Hydro Flask's Wide Mouth is a premium double-wall vacuum insulated bottle in 18/8 stainless steel. Most lids include a plastic inner component. The Flex Cap and Loop Cap have less plastic contact than the Straw Lid.
How scores are calculated
Materials (40%): How plastic-free the product is — raw materials, construction, and coatings.
Packaging (20%): Is the product packaged in plastic? Is it recyclable?
Transparency (20%): Does the brand disclose ingredients, sourcing, and manufacturing?
Durability (20%): How long does it last? Longer-lasting products reduce plastic waste over time.
This is a rating of this specific product only — not the company. Other products from this brand may score differently.

Plastic lids and gaskets on many Hydro Flask models mean some plastic still contacts your water, though far less than a plastic bottle.
Why We Rated It This Way
A significant upgrade over plastic bottles, but choose the Flex Cap or Loop Cap (not the Straw Lid) to minimize plastic contact with water.
