reusable to go cups for smoothies

[Guest guest]

I am looking for some good cups to use for smoothies on the go. My husband likes

to take his smoothies in the car in the mornings on his way to work. I also

don't always finish mind before leaving the house. It would be nice to have some

insulated cups with lids to put our smoothies in that fit in a standard car cup

holder. The only cups that I could think of that may work are Tervis Tumblers.

If anyone uses another cup that they like, please let me know what it is.

Thanks,

Kim
