The Hydro Flask 40 oz Wide Flex Cap Trillium is a large-capacity, double-wall insulated stainless steel bottle designed to keep beverages cold for up to 24 hours and hot up to 12 while resisting leaks and flavor transfer.

Built for long days, outdoor adventures, and heavy daily use, this 40-ounce Hydro Flask combines a wide-mouth opening for easy refills and ice with TempShield vacuum insulation to maintain beverage temperature. Its pro-grade stainless steel interior preserves taste, and the Flex Cap offers a secure, leak-resistant seal. Dishwasher-safe components make cleanup simple so the bottle stays ready for everyday use.

How does the 40 oz size fit into my routine?

This capacity suits people who want fewer refills during work, travel, or workouts. It holds enough water to get through several hours and accommodates large ice cubes for extended cooling.

• 40-ounce volume reduces refill frequency for long commutes or hikes
• Wide mouth accepts ice, powders, and fruit for customizable drinks
• Balanced weight distribution for carrying or strap attachment

What keeps drinks cold or hot inside the Hydro Flask?

TempShield double-wall vacuum insulation forms an airtight layer between inner and outer walls that limits heat exchange. That engineering greatly slows temperature change so cold stays cold and hot stays warm for many hours.

• Double-wall vacuum insulation minimizes thermal transfer
• Exterior stays comfortable to hold—no condensation with cold drinks
• Maintains drink temperatures without added ice or wraps

Is the Flex Cap really leakproof and easy to clean?

The Flex Cap is designed with a secure closure that prevents spills when closed, making it safe to toss in a bag. Both the bottle and lid are dishwasher-safe, simplifying maintenance and keeping the finish vibrant over time.

• Flex Cap seals tightly to prevent accidental leaks
• Dishwasher-safe components for hassle-free cleaning
• Durable materials retain finish and resist staining from beverages

Will this bottle affect the taste of my drinks?

Constructed from pro-grade stainless steel, the interior resists flavor absorption so past drinks won’t taint new ones. That means water, tea, or flavored beverages taste as intended without lingering aftertastes.

• Food-grade stainless steel prevents flavor carryover
• Easy-to-rinse wide mouth reduces trapped residue
• Ideal for switching between water and other beverages

Who is this for? The Hydro Flask 40 oz Wide Flex Cap Trillium is aimed at active commuters, outdoor enthusiasts, and anyone who prefers fewer refills and reliable temperature control. It suits students, office workers, hikers, gym-goers, and travelers who want a sturdy, low-maintenance bottle with a large capacity and dependable leak protection.
