Coolflask 64 oz Half-Gallon Insulated Water Bottle Arctic White with 3 Lids & Straw, Copper Vacuum

Coolflask 64 oz Half Gallon insulated water bottle with three interchangeable lids provides long-lasting temperature control and spill-friendly drinking options for gym, office, and outdoor days.

This Coolflask 64 oz (half-gallon) metal water jug combines a large-capacity design with vacuum insulation and a textured galaxy-style finish for a durable, attractive hydration solution. Built from 18/8 food-grade stainless steel with a copper-plated double-wall, it preserves cold beverages up to 48 hours and warm drinks up to 24 hours while resisting sweat and odors. The bottle ships with three purpose-built lids — twist spout, flip-up straw, and wide-mouth handle — so you can switch between fast gulps, hands-free sips, or easy refills and ice additions.

How does this bottle keep drinks cold or hot for so long?

The Coolflask uses a copper-plated double-wall vacuum structure and high-grade stainless steel to reduce heat transfer. That vacuum barrier limits warming or cooling from outside air, preserving beverage temperature without condensation on the exterior.

• Copper-plated inner wall for improved thermal retention
• Double-wall vacuum layer prevents heat exchange
• 18/8 food-grade stainless steel resists corrosion and flavor retention
• Manufacturer-tested: cold up to 48 hours, hot up to 24 hours

Which lid should I use for workouts, commuting, or desk use?

The included three-lid pack adapts the jug to different routines. Use the easy-twist spout lid for quick large gulps at the gym, the flip-up straw lid for hands-free sips while driving or working, and the wide-mouth handle lid for adding ice, powders, or easy refills.

• Twist spout lid: spill-reducing, ideal for fast hydration
• Flip-up straw lid: one-handed, convenient for active use
• Wide-mouth handle lid: simple refills and ice cube access
• Each lid designed to minimize leaks and improve usability

Is the bottle durable and safe for everyday use?

Yes — the Coolflask is made from rust-resistant 18/8 stainless steel and finished with a matte gradient powder coat with ice-speckle detailing to resist slips and wear. It's BPA-free and engineered to avoid retaining flavors, making it suitable for repeated daily use in varied environments.

• Food-grade 18/8 stainless steel construction
• BPA-free, odor-resistant interior preserves taste
• Matte textured coating reduces slipping from wet hands
• Laser-engraved logo and gradient finish for long-lasting aesthetics

How should I clean and care for this half-gallon flask?

To protect the vacuum seal and exterior finish, hand wash the bottle and lids with mild detergent; avoid abrasive scrubbers. Do not place the flask in a microwave or freezer, and be cautious with very hot liquids to avoid scalding.

• Hand wash only; no abrasive cleaners or steel wool
• Do not microwave or freeze the bottle
• Rinse lids promptly after sugary or flavored drinks
• Inspect seals periodically and replace if worn

Who is this for: The Coolflask 64 oz insulated half-gallon jug is designed for people who need all-day hydration without constant refills — athletes, commuters, office workers, outdoor enthusiasts, and anyone who prefers multiple lid options for different activities. If you value long temperature retention, a non-slip premium finish, and versatile drinking styles in one large-capacity bottle, this Coolflask model is a practical daily companion.
