OCTAROMA GRANDE AMBER YELLOW 435ML

Took this on a long hike and the 15 fl oz size was perfect—the vacuum insulation kept my tea warm for hours even in the cold wind. The lid seals tight with no leaks in my backpack, which is exactly what I needed for outdoor trips.

My coffee stayed piping hot through my entire morning commute and then some, which is exactly what I needed from a 15 oz mug. The vacuum insulation really holds up, and the lid seals tight enough that I can toss it in my bag without a single drip.

Took this on a long hike yesterday and the coffee was still steaming four hours later, which honestly impressed me more than I expected. The 15 oz size fits perfectly in my backpack's side pocket too, so it's become my daily sidekick.
