Titanium 350 Kanpai Bottle

The double-wall really works—my morning coffee stayed piping hot for over four hours during a chilly hike. And for something this sturdy, I keep forgetting it’s even in my bag.

The double-walled vacuum seal actually works — I filled it with coffee at 7am and it was still hot at lunch. It's so light I keep checking my bag to make sure I didn't leave it at home.

Took it on a hike last weekend and my tea was still hot four hours later, which genuinely surprised me. The double-walled vacuum seal really does its job, and it hasn't leaked once in my bag.
