NTK insulated thermos bottle

Nautika (NTK) is a prominent Brazilian brand specializing in camping, tactical, and outdoor equipment. Originally founded in Brazil in 1974, the company focuses on providing high-quality outdoor gear for the regional market.

While the brand is Brazilian, most of its technical hardware products, including insulated stainless steel bottles like the one pictured, are manufactured in China under strict quality control. The brand remains under the ownership of the Nautika group, which manages distribution across South America through its headquarters in Guarulhos, São Paulo.
