Coolflask 128 oz Gallon Water Bottle Insulated Jug with 3 Leakproof Lids — Triple-Insulated, Straw & Carry Handle

Coolflask 128 oz Gallon Water Bottle is a triple-insulated stainless-steel jug that keeps drinks cold up to 48 hours or hot up to 24 hours and includes three leakproof lids for sipping, pouring, or straw drinking.

Built from 18/8 (304) stainless steel and finished with an anti-sweat exterior, this 128-ounce water bottle is designed for long days, long workouts, and outdoor adventures where fewer refills matter. It comes with a screw-on lid with flip-up handle for easy carrying and ice access, a spout lid for controlled pouring and hot beverages, and a straw lid for convenient cold sipping. The jug is rustproof, BPA-free, and dishwasher-safe, making maintenance straightforward.

How long will the Coolflask keep my drink cold or hot?

The Coolflask uses double-wall vacuum insulation and triple-insulation design to minimize temperature transfer. Expect cold beverages to stay chilled for up to 48 hours and hot liquids to retain heat for up to 24 hours under typical conditions.

• Double-wall vacuum seal reduces heat exchange.
• Anti-sweat coating keeps the exterior dry and easy to grip.
• Stainless steel interior preserves flavor without odor retention.
• Performance varies with ambient temperature and how often the lid is opened.

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

The bottle includes three leakproof lids to suit different situations: a screw-on lid with a flip-up handle for filling and transport, a spout lid for controlled pouring or warm drinks, and a straw lid for hands-free sipping of cold beverages. Each lid seals tightly to limit spills and keep contents fresh.

• Screw-on lid with flip-up handle: ideal for refilling with ice and carrying long distances.
• Spout lid: better for pouring into cups or for sipping warm liquids safely.
• Straw lid: convenient for active use—runs, gym sessions, or desk hydration.
• All lids are designed to be leak-resistant when closed properly.

Is the Coolflask easy to care for and safe to use?

The Coolflask is made from food-grade 18/8 (304) stainless steel and is BPA-free, rust-resistant, and odor-resistant. It’s dishwasher-safe for most parts, though the manufacturer recommends avoiding the freezer and microwave and exercising caution when pouring very hot liquids.

• 304 stainless steel interior resists rust and flavor retention.
• BPA-free materials throughout all lids and components.
• Dishwasher-safe parts for convenient cleaning; hand wash recommended for prolonged lid life.
• Not suited for carbonated drinks; avoid microwave or freezer use.

How does the 128 oz size help during outdoor activities?

At 128 ounces (one gallon), this Coolflask reduces the need for frequent refills on long hikes, full-day events, or team practices. Its large capacity paired with high insulation makes it practical for sharing, long shifts, or multi-hour outings where staying hydrated without stops is a priority.

• One-gallon volume covers long outings or shared use for small groups.
• Flip-up handle and durable construction make it easy to transport.
• Triple-insulation maintains drink temperature across extended periods.
• Compact enough to fit in many vehicle cup holders when laid on its side and suitable for cooler storage.

Who is this for? The Coolflask 128 oz Gallon Water Bottle is aimed at outdoor enthusiasts, athletes, event staff, parents managing long days, and anyone who prefers fewer refills and reliable temperature retention. It’s a practical choice for camping, sports, travel, construction sites, and everyday home or office use where durability and easy maintenance matter.
