When S'well launched in 2010, the category it was entering did not yet exist as a design conversation. Water bottles were functional objects, expected to perform without being considered. S'well changed that premise by treating the everyday bottle as an object worth designing carefully — with materials, proportions, and surface treatments that reflected a considered point of view rather than default manufacturing. The 17oz original remains the clearest expression of that position.

The Therma-S'well triple-layered vacuum insulation keeps beverages cold for 36 hours and hot for 18, with a copper wall layer that prevents condensation from forming on the exterior. The body is 18/8 food-grade stainless steel, BPA and BPS-free throughout. At 17oz the bottle occupies the same visual footprint as a standard plastic bottle while dramatically outperforming it on every temperature and material dimension. The opening is wide enough for most ice cubes. It fits standard cupholders and most bag side pockets. It is available in an extensive range of finishes and patterns. Hand wash is recommended to preserve the exterior. For those who want their hydration objects to reflect the same level of care they bring to everything else they carry, the S'well 17oz is the original answer.
