Polar Bottle furthers its innovation in the hydration market with it’s colorful new insulated water bottle series — Ergo Spectrum. Spectrum is the latest addition to the Ergo Hot/Cold bottle line, which updates the Polar Bottle dual-wall insulation design with a new harder plastic that works to insulate both hot and cold liquids. Available in a range of bold colors — from bright red to lime green, blue and charcoal grey — the sleek Ergo Spectrum line has a bottle for every personality and lifestyle. Unlike many competing hot/cold insulated bottles, the 22oz Ergo is lightweight and compact, making it the ideal everyday hydration accessory. The bottle’s innovative Half Twist Cap™ design delivers supreme water flow, while a medical-grade silicon gasket seals the cap to deliver a no-spill, no-leak drinking experience. Continuing the Polar Bottle tradition, Ergo Spectrum is Made in the USA, BPA-free, Phthalate-free and ultimately recyclable.
