Portable smoothie cup?

Has anyone ever tried using their free sip for smoothies on the go? Thoughts comments? Or maybe the twist or tumbler cups?

!! I am open to other cup suggestions as well as long as they are insulated! Looking at mostly Owala (my love) Stanley and maybe simple modern since I heard they’re also leak proof?

I want to start packing my smoothies overnight to work since I don’t always have the chance to eat and it would also be nice to pack husband one for work since he works outdoors
