IRON °FLASK 64 oz Wide Mouth Water Bottle with Straw — Insulated 18/8 Stainless Steel, Leak‑Proof, 24‑Hour Cold

IRON °FLASK 64 oz Wide Mouth Water Bottle with Straw is a double-wall insulated, stainless-steel jug designed to keep beverages cold up to 24 hours or hot up to 12 hours while offering leak-proof straw sipping and easy portability.

This 64-ounce wide-mouth water bottle from IRON °FLASK blends heavy-duty construction with everyday convenience: a vacuum-insulated 18/8 stainless steel body prevents sweating, a leak-proof straw lid with carabiner clips to bags, and a large capacity that reduces refills during long outdoor trips, workouts, or busy days. It’s built to resist rust and metallic tastes, and the wide opening simplifies filling, cleaning, and adding ice.

How long will beverages stay cold or hot in this bottle?

The bottle uses double-wall vacuum insulation to preserve temperature. Cold drinks stay chilled for up to 24 hours and hot drinks remain warm for up to 12 hours under normal conditions, making it useful for extended outings and long workdays.

• 24-hour cold retention with ice-friendly wide mouth
• Up to 12 hours for hot liquids
• Insulation prevents external condensation or “sweat”

Is the straw lid really leak-proof and easy to carry?

The included straw lid is designed for spill-free sipping and features a secure seal to limit leaks during transport. A built-in carabiner lets you clip the bottle to backpacks or gym bags for hands-free carrying when on the move.

• Leak-resistant straw lid for upright and casual use
• Carabiner attachment for quick clipping to bags or gear
• Straw allows sipping without fully removing the lid

What materials and care instructions should I know?

IRON °FLASK uses food-grade 18/8 stainless steel that resists rust and avoids imparting metallic flavors. To maintain the finish and insulation performance, hand wash with hot soapy water only; avoid dishwashers which can harm seals and exterior coatings.

• Made from BPA-free, 18/8 stainless steel
• Hand wash recommended; do not use abrasive cleaners
• Wide mouth makes cleaning and ice insertion easy

Why choose the 64 oz size instead of a smaller bottle?

A 64-ounce capacity minimizes refill stops for long activities like hiking, road trips, or full-day work shifts. The larger volume is ideal when you need sustained hydration or want to carry a mix of water and chilled beverages without frequent top-ups.

• Reduces refills during long outings or multi-hour workouts
• Large opening for ice, powder mixes, or chilled fruit infusions
• Durable enough to handle daily use and outdoor conditions

Who is this for? The IRON °FLASK 64 oz Wide Mouth Water Bottle with Straw suits athletes, outdoor enthusiasts, commuters, and anyone who prefers fewer refills during busy days. It’s a practical pick for people who want a rugged, temperature-retaining bottle with a convenient sipping straw and a carry clip. If you prioritize large capacity, reliable insulation, and easy transportability, this bottle is built to match those needs while resisting rust and unwanted flavors.
