This is the thermo cup called "thermos cup with straw" (see picture) I was positively surprised by. Many people including me have this "stainless travel cup" and it is also very good. Here are the advantages and disadvantages of these two and tips for other cups .
Stainless travel mug:
Advantages: 1.2 l capacity, retains heat and cold well, has a good handle, option for straws, can buy lots of extra accessories, dishwasher safe
Cons: A bit big to carry in your bag, plays a lot without extra cover accessories, needs long plastic straws
Thermos cup with straw
Advantages: 9 dl capacity, retains heat and cold well, leak-proof lid, can be carried in your bag, some extra accessories can be purchased, can use most straws, comes with a metal straw
Disadvantages:
Slightly less capacity, slightly less extras, no handles
Otherwise, there are many other nice thermoses in the store and also thermoses and bottles at this link:
