Yeah, my current favorite bottle is the yeti, but it still has plastic for the lid. If they ever made a stainless lid it’d be pretty close to the perfect bottle. Wide mouth that’s super easy to clean, indestructible, replaceable seals, doesn’t alter the flavor of the water, even after multiple days. Any bottle with a mouth that doesn’t let me get my hand to the bottom, or doesn’t let me see every part of every internal surface isn’t cleanable enough for me.
