Made from pro-grade stainless steel, this bottle ensures a pure taste without any flavor transfer from previous contents. Its double-wall vacuum insulation can keep drinks cold for up to 24 hours and hot for up to 12 hours, making it perfect for all-day use in various environments.

Its leak-proof design, thanks to the Flex Cap, provides peace of mind when carried in bags or backpacks, preventing unwanted spills. The bottle is also dishwasher safe, simplifying cleaning and maintenance and ensuring that it remains hygienic and ready for use at all times.

However, the bottle's weight of 335 grams might be a bit heavy for some users, especially when filled with liquid. Additionally, while the stainless steel construction is robust, it might not be as lightweight as some plastic alternatives.
