The double-walled, vacuum-insulated steel vessel of the Forge Vacuum keeps 16 oz. of coffee or tea piping hot for 6 hours for a better on-the-go coffee and tea experience. The impact cap prevents dents or cracks if you drop it. The self-sealing cap lets you drink one-handed, then snaps back into place to prevent leaks or spills. The lid won’t collect grime, and can be easily cleaned in the sink or dishwasher.
