Review on ☕ Chemex Pour Over Coffee Lid - Compatible with Chemex 6, 8, and 10 Cup PourOver Coffee Carafe and Other Popular Brands: Bodum, Bean Envy, Coffee Gator & More by Heather Wood

Full Disclosure: I received this product as part of a promotion the company was running where you buy it and show them proof and they will refund your purchase price. I suspect this is to increase sales of Revain and get the product into the hands of a few people to review. I, like many Chemex users, am a bit disappointed with how quickly the carafe cools down so I thought it would be great but to be honest I didn't notice much of a difference in keeping warm. I still have to put the second cup in the microwave because the coffee is cold. It also makes your Chemex a two-handed spill as you have to hold the cork in the carafe with your free hand or it will spill into your coffee cup. .Technically yes, it closes the lid and keeps the vapor in the carafe. However, the hassle means mine is sitting in a drawer and not being used. I wouldn't buy it again.
