FLSK Drinking bottle

Thanks to the unique Vacuum Isolated Copper Coating Technology, the FLSK thermos bottle keeps your drinks 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, an extra 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 yet 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 stainless 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.
