リサイクルスチール製保温ボトル、アースブラウン

Filled it at 7am and the water was still icy cold at midnight, which is exactly the 48 hours they promised. The recycled steel finish has this nice matte texture that doesn't slip in my hand, even when it's condensation-covered.

My coffee was still steaming at 6pm after pouring it at 7am—the 20-hour heat retention is no joke. The recycled steel body feels sturdy without being heavy, though the earthy brown finish does show fingerprints more than I'd like. Still, it's become my daily desk companion.

Took this on a weekend camping trip and the coffee was still steaming at sunrise the next day. The recycled steel feels solid and the matte brown finish hides scratches well, which is a bonus when you're tossing it in a backpack.
