Meet the ThruBottle - a lightweight, one liter bottle with a 28mm neck that's designed to be reused. 

The ThruBottle is the result of multiple years of design, testing, and refinement. The final product is a patent-pending, one liter bottle that’s lightweight, slim, and safe to use over the course of a long hike. Designed with ultralight backpackers in mind, it's constructed from safe, durable materials intended for long-term use - even through long periods of sun exposure and rough conditions. 

The ThruBottle utilizes the same universal thread as the Vecto, ensuring it's 28mm neck will be compatible with a wide range of 28mm filters.
