Quick review here for a simple product, but one we appreciate because it works with our espresso machine. Pour a couple shots (or three) cap it and off to the office, the races, or ride meetup.
Innate made the Doppio Tumbler for their friends and my question was, “for bicycle bottle cages next please.”

Find more Innate gear on Amazon.com. The Doppio is available direct from Innate for $9.00 CAD.
My beef with this is that espresso should never be taken to go. It’s such a sensitive drink, it should be enjoyed within a minute of brewing (ideally within seconds). Anything longer than that and it goes sour.
Noted and my trips with this are from the kitchen to the studio . . . it’s intended for lattes and the like.
