Espresso Duo™ 3oz/100ml

The double wall glass really does its job—my espresso stayed hot through a long phone call, and the outside never got too warm to hold. The little silicone valve on top is a nice touch too, no annoying pressure buildup when I screw the lid on. Exactly what I needed for slow mornings.

I love that the patented air silicone valve actually works—no more fighting with a stuck lid or dealing with condensation on my countertop. The double wall keeps my morning latte steaming for almost an hour, which is perfect for slow sipping.

I was surprised how well this little cup keeps my espresso hot even while I'm sipping slowly. The double wall design works perfectly, and the glass itself feels really solid.
