ゼブラング アウトドア二重壁コーヒーマグ

I've been using this mug every morning for a week, and the double-wall insulation keeps my coffee hot for at least a couple of hours, which is way better than my old ceramic cup. The stainless steel body feels sturdy and the mesh filter catches the grounds perfectly without slowing down the pour.

The mesh filter does its job perfectly, letting through just enough oils for a rich taste without any grit. I brewed a cup this morning and it stayed pleasantly warm for over an hour, which is exactly what I needed for my slow mornings.

I was skeptical about brewing coffee directly in a mug, but the double-wall insulation keeps it hot for a surprisingly long time without burning my hands. The mesh filter lets through just enough oil for a smooth cup, and it’s easy to clean.
