As a coffee devotee, I’ve tried my fair share of reusable travel mugs over the years, but this one is by far the best. You probably know Owala for its fun-coloured water bottles, but its sleek travel mugs are equally worth the hype. Owala’s SmoothSip tumbler features a splash-resistant lid and double-wall insulation, keeping drinks hot for up to 6 hours and cold for up to 24 hours. I fill it with hot coffee every morning on my way to the office, and by the afternoon, if I haven’t finished it, I’m always impressed that it’s still very warm. My favourite feature, though, is its completely leakproof lid. I comfortably toss it in my backpack without any worry of it spilling all over my laptop. I even give it a good shake to mix my coffee and milk together, and there are never any leaks. My only con is that the brand recommends you hand-wash the tumbler to keep its exterior in good condition (but truthfully, I’ve put it in the dishwasher a few times and it has held up just fine). It’s also available in a smaller 12-ounce version. Meaghan Kenny
