i kno this is a hi protien / modified fast forum but i am hoping to tap your experience on this. i need to carry my veg/fruit smoothie to work every day. i have my protien shakes for breakfast but i need something more satisfying for my workday. do u take a thermos type container? i cant quite find a good secure vessel for my puke-green snack and lunch! o, and it would be good if it was opaque....refer back to the puke-green comment...

How about a stainless steel thermos ?
