First we introduced the world to PURSUIT, FORM is the next step in the evolution of the shaker bottle. FORM is a hybrid bottle, engineered for protein shakes, infusions and hydration. Designed for purpose and built to last. PROMiXX is devoted to sustainability and carbon neutrality. FORM is constructed of the same bio-copolyester, ECOZEN, as many of our other products. Proven to be tough and durable, and in the hands of thousands of users worldwide. ECOZEN is a carbon neutral material, far superior in its function, and more environmentally-friendly than your regular bottle. As a brand, we strive to create better products in a better way. Whilst FORM is an aesthetic and functional evolution of the PROMiXX shaker bottle line, it still packs a punch: durable, odour and stain resistant and BPA-free, which means your drinks stay clean. Designed and engineered with a sleek and flowing ergonomic presence, FORM fits comfortably and securely in your hand. Combine the elegance of the bottle, with the purposefully deigned mouthpiece - you get a bottle that is a pleasure to use. As with ALL PROMiXX products, FORM is also guaranteed leakproof.
