I love my Tervis Tumblers. I really do think they are an essential part of college. Carry this reusable tumbler wherever you go. It's eco-friendly and keeps your drinks hot or cold without any condensation. You can also change the lids. They have a to-go lid and a lit with a straw. I love that they are personalized and they even have a bunch of different logos for different schools! I seriously use my Tervis every single day while I am at school. I fill it with hot coffee in the morning, diet coke or iced tea in the afternoon and then hot tea or coffee at night.
Camelbak water bottle. I also use this daily. I had one that lasted me all throughout my freshman and sophomore year and now I have two that I alternate between. I keep one filled up and in the fridge and one on the go... that way I'll always have a full, cold water bottle on hand! They have a newer one called the Groove where it actually filters the water in your bottle as you drink it. Might just have to invest in one! They also have neoprene sleeves available so that the condensation doesn't get all over the place!
What do you drink your beverages out of on the go at school? Have a fabulous day!
