12-ounce Coffee Mug, $29.95, available in 5 colors at Amazon and
Hydro Flask
I'm usually strictly a water drinker at work, but I've been drinking a lot more tea and cold brew ever since getting this mug. When I want a warm beverage, like a soothing cup of green tea, this mug keeps it hot — almost too hot. I actually leave the lid open for a little bit before tightening it so I can drink my tea without scalding myself. And when I'm feeling a refreshing cold brew, it keeps my jolt of caffeine cold all afternoon. It's really comfortable to hold, plus the spout lid prevents accidental spills. I'm going to need another one of these to use at home. Yes, it's that useful. —Connie Chen, Insider Picks reporter
I bring this mug with me everywhere at work — to every meeting, to lunch, to a coworker's desk and back. It basically never leaves my sight. It keeps my coffee warm for hours when I'm too focused on something else to remember to drink it. The spout on the lid doesn't have any sort of top that seals so I don't love taking it on the subway, but I do love that it's sealed enough that I can walk to meetings quickly without worrying about spilling.
The real mug shape also makes me feel ... settled in, if that makes sense. I mean, I suppose that's a weird way to put it, but when I drink from tumblers and travel cups, I always feel like I'm on the go in a way I don't want to be once I've gotten into work and settled for the day. —Sally Kaplan, Insider Picks editor
