FLSK Drinking bottle

The unique Vacuum Isolated Copper Coating Technology keeps the FLSK thermos bottle's beverages cold for up to 24 hours and hot for up to 18 hours. A vacuum layer between the stainless steel prevents the escape of heat or cold, as it does not conduct like air. Additionally, a copper coating on the stainless steel ensures temperature retention. The perfect temperature - always and everywhere. The insulated bottle combines high technical standards with perfect design, making it a highly functional and visually appealing drinking bottle. The FLSK thermos bottle is lightweight, handy, and available in three different sizes. The lid is completely leak-proof – no more spills. Furthermore, the insulated bottle is carbonated beverage safe, taste-neutral, and completely BPA-free and environmentally sustainable. The high-quality craftsmanship from rust-resistant and taste-neutral type 304 stainless steel ensures that your new FLSK becomes a long-lasting, reliable companion that you won't want to be without.
