Hydro Flask 64 oz Wide Mouth Water Bottle - Long-Lasting Cold

In this review the Hydro Flask 64 oz Wide Mouth with Flex Straw Cap stands out as a simple, heavy-duty choice for anyone who needs large-capacity hydration on the move. The single biggest reason to buy is its combination of reliable 24 hours cold TempShield insulation and a closeable, portable straw cap that makes one-handed sipping easy. For long outdoor days, long shifts, or family use where one big bottle reduces refill trips, this bottle keeps drinks cold, resists flavor transfer, and is built to last in everyday use.

Key Features

• 64 oz capacity: Carry a full day of water or share among two people without constant refills, reducing interruptions during outings or work.
• TempShield insulation: Double-wall vacuum insulation keeps contents cold up to 24 hours for sustained refreshment on hot days.
• Flex Straw Cap: The closeable, leakproof straw cap opens for one-handed sipping and clicks shut to prevent spills when tucking the bottle into a bag.
• Durable stainless steel: Pro-grade stainless construction resists flavor retention and keeps drinks tasting fresh from morning to night.
• Dishwasher safe: The bottle and disassembled straw lid can go in the dishwasher, making it easy to keep bright color and clean internals.
• Monochrome look: Color-matching lid and logo give a coordinated appearance that stays vibrant through normal use.

Who It's For

The bottle is ideal for outdoor enthusiasts, workers on long shifts, or parents who prefer one large refillable bottle to reduce single-use containers. It suits people who need reliable cold retention and a straw cap for convenient sipping without removing the lid.

Those who want a very compact bottle for tight cup holders or who primarily drink hot beverages should look elsewhere, since the Flex Straw Cap is not intended for hot liquids and the 64 oz size is large for restricted-storage situations.
