An Overview On Insulated Coffee Mugs

For many people, beginning the day without a hot cup of coffee or tea just doesn’t feel right. Not only do you need that nice jolt of caffeine, but there is something comforting about holding a warm beverage and following through with a daily ritual. However, being able to sit calmly at home and enjoy a cup of coffee or tea in peace isn’t always possible. You have to run to work or school, or around town to complete errands. When you still want that delicious warm beverage, it’s time to get an insulated coffee mug.

An insulated coffee mug is a special vessel that is designed for drinking warm or cold beverages on the go. It keeps heat or cold inside the mug so that your coffee or tea don’t change temperature. Plus, the insulated coffee mug comes with a handy lid, which is often leak proof, so you can guard against spills while you’re out and about.

Insulated coffee mugs are ideal for those who are looking to reduce waste, cut costs and make their morning routine more efficient. By making your coffee or tea at home, you can save several dollars each day. You can also avoid having to wait in line at the coffee shop, or throwing out disposable cups.

The Insulated Coffee Mug Buying Guide

  • One of the most important things to look for when buying an insulated coffee mug is whether or not it has a leak-proof lid. If not, you may end up with hot coffee or tea all over your lap, or drips on your shirt. Look for insulated coffee mugs with a tight-sealing lid that is designed to keep liquid inside. It’s also handy when the lid is leak proof even if the cup is not vertical. That way, if your cup falls over, your beverage will stay safely inside.
  • Insulated coffee mugs come in different shapes and sizes. If you like to drink a few cups of coffee or tea each day, opt for one that can accommodate that. Insulated coffee mugs can be found in 10, 12, 14 and 20 ounce sizes.
  • If you drive often and like to enjoy your coffee or tea in the car, then the shape of your insulated coffee mug is important. Be sure to get one that can fit in easily into your cup holders. Some insulated coffee mugs are too wide to fit into a standard cup holder, so be sure to note the measurements.
  • Handle or no handle? This is a personal preference, so decide what you prefer. Keep in mind that insulated coffee mugs with a handle may not fit properly into your car’s cupholders.
