Isosteel VA 9562DQAT Duo Vacuum Flask Titanium Gray 1.0L of 18/8 stainless steel with Quick Stop Einhandaus ... and 2 removable drinking mugs (household goods)
Hey, have the bottle now get (super delivery btw.) and they like it very much. Nice design, according to the manufacturer "unbreakable" and I think so too. However, it is quite large, so be aware of all dimensions! They can also use well without lower cup, so it fits nicely into a backpack and will keep me in various university lectures awake. Just to know;)
