Coolflask 40 oz Insulated Water Bottle with 3 Lids — Vacuum Stainless Steel, Keeps Cold 48H / Hot 24H

All-day hydration, built to last

Meet the Coolflask 40 oz insulated water bottle, a durable companion designed for everyday use. Crafted from 18/8 (304) stainless steel, it is BPA-free, rust-proof, and built to resist odor transfer, helping you enjoy a clean-tasting drink from the first sip to the last drop. The exterior features an anti-sweat coating, keeping the surface dry and comfortable to hold even when beverages run cold.

Triple insulation with a double-wall and vacuum seal creates a robust barrier against temperature changes. In real-world terms, beverages can stay cold for up to 48 hours and hot for up to 24 hours, depending on the environment. This design minimizes condensation on the outside and helps you maintain a comfortable grip during activities or commutes.

Care and use

Maintenance is straightforward: rinse and hand wash with mild soap, avoid abrasives, and do not place the bottle in the freezer or microwave.
