Avanti 360 GoCup 355ml/12oz Gunmetal

I have owned one of these screw top cups for over 5 years. It gets used every day. Unlike other travel mugs you don't burn your tongue when drinking as you can slurp cooling air as you drink. Also the mug has no ancillary air vent so when closed is fully water tight. There is no handle to get in the way and you can drink from any position around the rim. The only negative is that when the mug is sealed shut on a very hot drink it vaccum seals and becomes hard to open until the drink cools. The positive is that the sealed mug can be carried in a bag without leaking. This is the only mug I ever recommend.
