Why we picked it
A 600ml borosilicate glass bottle with a stainless steel lid, and the brand states the water has full glass and steel contact. Glass is inert, easy to inspect for residue and does not hold flavours.
Best for
People who want water to touch only glass and steel, and like to see what is inside
Not for
Rough outdoor use, toddlers or anywhere a drop onto stone is likely
