Oztent Alpine 雙層隔熱咖啡杯

Took this cup on a weekend camping trip and my morning coffee was still warm three hours later. The double-wall insulation really works, and the size is perfect for a strong brew.

I work at a desk all day and was tired of lukewarm coffee by 10am, but this cup actually kept my drink hot for nearly three hours straight. The double-wall insulation makes a huge difference, and the lid fits snugly enough that I can toss it in my bag without any leaks.

Filled it at 6am and my coffee was still properly hot at 9 during a frosty morning sit. The double wall means no burnt fingers either, which I didn't expect to appreciate this much.
