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've been using this tumbler for my morning coffee and it stays hot for hours, which is exactly what I needed. The double wall insulation really works, and the cupholder-friendly base fits perfectly in my car.

The twist-on lid seals tight enough that I can toss this in my bag without a single drop leaking. The two straws are a nice bonus, and the vacuum insulation keeps my iced coffee cold all the way through a long afternoon.

Picked this up for my morning commute and it fits perfectly in my car's cupholder, which is a nice bonus. The double-wall insulation keeps my coffee hot for a solid couple of hours, though I wish the lid were a bit more spill-proof when jostled. Still, the two straws are a thoughtful touch.
