xMeet your everyday hydration partner
The Hydro Flask 40 oz Wide Mouth Bottle with a closeable Flex Straw Cap blends rugged, travel-ready durability with thoughtful design. Crafted from pro-grade stainless steel, it helps keep beverages cold for extended periods and is designed for one-handed use, so you can sip on the go without slowing down. The bottle is BPA-free and finished to stay bright, clean, and ready for your next adventure.
With its TempShield double-wall vacuum insulation, this bottle is built to chill your drink for hours while remaining lightweight enough to tote through a commute, gym session, or outdoor excursion. The wide mouth accommodates ice cubes and makes filling and cleaning a breeze.
While the Flex Straw Cap seals securely when closed, it is not intended for hot liquids, and the bottle should not be used on stoves, in microwaves, or freezers. This bottle is designed for everyday use, and its durable construction aims to resist odor buildup while preserving flavor with every sip.
