Coolflask Half Gallon Insulated Water Bottle 64 oz — 3 Leakproof Lids, Triple-Wall Vacuum

The Coolflask Half Gallon insulated water bottle is a 64 oz stainless-steel jug that keeps drinks cold up to 48 hours or hot up to 24 hours and includes three leakproof lids for versatile drinking.

This large-capacity Coolflask combines 18/8 food-grade stainless steel with a triple-wall vacuum design and an anti-sweat finish to deliver durable, flavor-neutral hydration for long days outdoors, workouts, or busy routines. It ships with a screw-on lid with a flip handle for easy refilling, a spout lid suited for warm beverages, and a straw lid for hands-free sipping of cold drinks, so you can choose the opening that best fits the moment.

How long will this bottle keep my water cold or hot?

The Coolflask uses triple insulation and vacuum sealing to slow temperature transfer: expect cold beverages to stay chilled for up to 48 hours and hot drinks to remain warm for roughly 24 hours in typical conditions. The anti-sweat coating prevents external condensation, keeping the bottle dry to the touch.

• Triple-wall vacuum insulation for extended temperature retention
• Anti-sweat coating avoids slippery surfaces and water rings
• Stainless interior won’t retain odors or flavors

What lids come with the bottle and when should I use each?

Coolflask includes three interchangeable, leak-resistant lids so you can adapt to different activities: a wide screw-on lid with flip-up handle for adding ice or cleaning, a spout lid for controlled pours or warm beverages, and a straw lid for easy sipping during cardio or desk work. Each lid locks tightly to reduce spills while transporting.

• Screw-on lid with flip handle — best for ice, refills, and hauling
• Spout lid — ideal for warm drinks or measured pouring
• Straw lid — convenient for hands-free hydration while moving

Is this bottle easy to clean and safe for everyday use?

The 64 oz Coolflask is made from 18/8 (304) food-grade stainless steel, which resists rust and won’t hold onto odors, making it suitable for daily use. It is dishwasher-safe for routine cleaning, but avoid freezing or microwaving, and take care when handling very hot liquids to prevent scalds.

• 18/8 stainless steel interior — hygienic and odor-resistant
• Dishwasher-compatible components for convenient cleaning
• Avoid freezer or microwave use; follow safety suggestions for hot liquids

How practical is this bottle for travel, sports, or outdoor activities?

With a 64 oz capacity, the Coolflask reduces refill frequency and supports longer activities like hiking, camping, long commutes, and tournaments. The robust construction and portable flip handle make it easy to carry, while the range of lids adapts to different situations from icy hydration to warm beverages on chilly mornings.

• 64 oz (half gallon) volume minimizes stops for refilling
• Durable stainless steel body withstands outdoor use
• Flip handle and leakproof lids improve transportability

Who is this for?

If you need a rustproof, reusable bottle that keeps drinks tasting fresh and lets you switch between sipping styles, this Coolflask is a versatile pick.
