@@judyrivait2020 No, I have not have mold issues. I used to have them in a plastic water bottle from Lorna Jane when I put lemon in it…it’s one of those infusion type of water bottle. Not this one so far…
Hi…so far I have only use my Hydroflask Travel Tumbler for coffee(I replaced it with sipper lid). I only use my Hydrojug for my car. What I like about this one being in the car, their lid is see through, so I can see if I’m running low on water.
They have bags that you can now carry your tumbler on your shoulder like a shoulder bag, because you’re right they are heavy and I like to put my tumbler in a bag. It’s called a Tumbler bag when I go to the gym.
