ボイジャー タンブラー（クリアフリップリッド＆ストロー付き）

I was pleasantly surprised by how well the double-wall insulation worked—my iced coffee still had ice cubes after three hours in the sun. The straw is sturdy and the lid seals tight enough to toss in my bag without a worry.

The flip lid really does lock on tight—no spills in my car’s cupholder. I’ve been sipping my coffee for two hours and it’s still pleasantly warm. The included straw is a nice bonus for easy drinking on the go.

The double-wall insulation kept my iced coffee cold for a full workday, which was exactly what I needed. The flip lid seals tight enough to toss in my bag without a single leak. The two straws are a nice bonus too, since I always misplace one.
