Query: Good Sport Top, Tight Seal, No Metallic Taste

The kanteen is just as I wanted it to be and the sport cap is well made with a tight seal. I would have given it 5 stars except that one of the two I ordered makes an odd noise when I drink from it. I think it has something to do with the tiny plastic air vent in the top, as the other one is quiet.
