Winter is officially here, and with it come cold mornings when your coffee goes lukewarm before you reach the car. A good insulated mug fixes that, and tortoiseshell travel mugs look smart doing it. Here are four tortoiseshell picks from Simple Modern and Ello, ranging from a classic mug to a big bottle for all-day sipping.
The brown and amber pattern goes with cozy knits and wool coats, so these make easy winter gifts too. Pair one with the soft throw from our winter blanket pick, and you have a ready-made cold-weather kit. For more gift ideas, see how to shop Amazon smarter this holiday season.

The Ello Magnet 18 oz travel mug in Tortoiseshell is the one to toss in your bag. Its slider lid seals inside the mug, making it leakproof and splash-resistant, and Ello rates it to keep drinks hot for up to 5 hours and cold for up to 10. The cork side handle gives you a steady grip, and the cork base protects your desk and fits cupholders. All parts are BPA-free; the lid is top-rack dishwasher safe, and Ello recommends washing the body by hand.

Not everyone switches to hot coffee in December. The Simple Modern Iced Coffee Tumbler 24 oz in Tortoise comes with a straw and a tapered shape that fits most cupholders. Double-wall insulation keeps the outside dry, so it won’t leave a ring on your desk or car seat. A silicone gasket holds the straw in place to reduce splashes. Simple Modern calls it spill-resistant, not leakproof, so keep it upright in your bag.
