Sleek, functional with all the details thought through.  We can't speak highly enough of Kinto's Travel Mugs, pick either the 12 or 17 oz depending on your needs.

It has two removable caps, the top cap protects the tumbler from dirt and leaking.  The second cap provides easy drinking from any angle while protecting you from ice cubes hitting you in the nose or a dousing of coffee on your shirt while you go for the last sip.

The actual tumbler is made of durable 18-8 double walled stainless steel and keeps liquids cold and hot for up to 6 hours.  It is a pleasure to drink out of and looks so good.  It will make you feel good about bringing your beverages with you, helping you avoid plastic bottles.

And of course it is BPA free.
