Since I am at the college for long periods of time I bring a cup of whatever I want to drink that day. I recently bought this Eagles tumbler off of amazon so I could carry tea or water to classes. These have a lifetime warranty and are good for cold and hot drinks. I love these things. I have one in a 24 ounce like shown an received one from camp last year with a customized Camp O blue logo in a 16 ounce.
I just made myself a cup of coffee and poured it in there so I could drink it at my leisure instead of it becoming cold in a regular cup like what mostly happens. Burnt my lips too even after a considerable period of time. Quite handy I must say. If you need travel mugs for anything I suggest you get these. Well worth the money.
I only wish the Eagles had a lifetime warranty on some of their players because we suck this year :/
