This strange water bottle is designed to ride faster
Tazi, an American company, has reinvented the water bottle with a curious design that is born with aerodynamics in mind, in addition to trying to facilitate liquid intake and filling.

Tazi Reinvents the Water Bottle
The Tazi RZ is a water bottle that will not go unnoticed on any bike. It is designed with a curvature at the bottom to improve aerodynamics, adapting as best as possible to the area between the down tube and the seat tube of the bike. Unusually, the nozzle of the bottle is located at the bottom, meaning it is positioned upside down in the bottle holder. In any case, it can also be placed in a conventional position, although some aerodynamic advantages may be lost.
By the way, this Tazi RZ bottle is designed to fit in the vast majority of bottle holders on the market.

Apart from the aerodynamic improvements that this bottle claims, it also facilitates hydration. Firstly, being upside down allows for a natural grip and consumption without having to twist the wrist. Secondly, the angled shape of its mouth allows for more effective filling at taps where the bottle may not fit, ensuring it can always reach its slightly more than half a liter capacity.
This Tazi TZ bottle is priced at €15.22 on the brand's official website.
