Known product problem and Hydroflask doesn't honor warranty!
I wish I could have given a negative star rating! My hydroflask mug discolored on the bottom AND on the mug, and turns out they know this is a product problem. They do NOT make good on their warranty, and require that you : 1. send photos of the problem (no issue with that), but THEN, 2. send a VIDEO of you writing 'no warranty' on the mug in ink, destroying it before they replace it. When I said that was unreasonable since they had a pdct issue that they needed to correct, they kept adding what I needed to do to get a replacement, so I gave up. Life is too short. Don't buy hydroflask!
