不鏽鋼水壺

My morning coffee was still piping hot when I finally got around to drinking it at lunch, and the lid seals completely shut with no drips even when I toss it in my bag sideways. The double-wall really does its job.

Took this on a day hike and the water was still cold after 6 hours in direct sun, which impressed me. The double-wall construction is no joke, and the cap seals tightly enough that I'm not worried about leaks in my bag.

Was skeptical about the leak-proof cap but I tossed it in my gym bag sideways and not a single drop escaped. Ice water stayed cold through a full afternoon of errands, and the 17-ounce size fits in my car cup holder perfectly.
