Drink from Glass.

It tastes better, and it’s better for you.

The problem

Microplastics are everywhere—especially in bottled water

Tiny plastic fragments can shed from containers and caps into your drink. Heat and abrasion increase shedding, and once they’re in, you can’t “filter out” what you’ve already swallowed.

  • Plastic bottles and caps can release particles during transport, storage, and reuse.
  • Hot cars, dishwashers, and vigorous shaking accelerate shedding.
  • Glass doesn’t shed microplastics—ever.

How plastic sheds

Friction + heat + time = particles

Plastic is convenient but fragile at the microscopic level. Everyday handling—twisting caps, squeezing bottles, tossing in bags—creates wear that releases tiny fragments.

  • Temperature swings (car to fridge) stress plastic
  • UV exposure and detergents can degrade surfaces
  • Reusing thin bottles increases risk over time
Why glass wins

Glass is chemically inert and doesn’t shed plastic—so your water tastes the way it should. Our protective sleeve keeps it safe on the go.
