I actually went with the flip lid by hydroflask with the straws. But I didn’t like the straw it made my water taste funny. What I do like about the hydroflask lid is that the straws are optional. Once I took the straw out and off it worked great. The flip lid however does sweat but the bottle does not. Rebecca
Hydro Flask sports top leaks if turned upside down. It even says not leak-proof on specs. I am not sure about Coldest tops. I am searching this thread to see if leak-proof. I have the Kleen Kanteen top and it works on my Hydro Flask and does not leak. I don’t use the straw with any top because I don’t like t clean them. I am getting this bottle because it has a better price point than hydroflask. At the rate I drop and break them, I need a more economical price tag.
