Why we picked it
One of very few mainstream bottles made from only stainless steel, bamboo and food-grade silicone, so water touches steel and a silicone seal only. Klean Kanteen states its range is 18/8 steel and lead-free.
Best for
Everyday cold water with no plastic anywhere in the bottle or cap
Not for
Hot drinks on the go, as it is single-wall and not insulated
