The Camelbak Forge® Vacuum Insulated 16oz Travel Mug is a double-walled, vacuum-insulated steel vessel that keeps 16 oz. of coffee or tea piping hot for 6 hours, with an impact cap that prevents dents or cracks if you drop it. The Forge is designed to fit in most cup holders, but the leak-proof cap means you can also toss it into your pack without soaking your gear. When you need to keep your eyes on the road, the self-sealing cap lets you drink one-handed, then snaps back into place to prevent leaks or spills. For frequent sipping, just press the top button to lock the cap open. The lid won't collect grime, eitherjust pop up the arms for easy cleaning in the sink or dishwasher.
