Since 2013 Stanley stainless vacuum bottles have been keeping things hot, and cold. Now, they've developed a one-pot coffee press.
Their new vacuum coffee system has it all: a pot for boiling water, a French press, a vacuum bottle, plus two cups and a compartment to stow your favorite grind.
Everything locks or screws together too. It's easy and efficient. Their Mountain Coffee System (MSRP $60) is rust-proof stainless steel, and will make a full liter of great, hot coffee. Just boil the water in the bottom stainless shell. Then pour grounds in the water and let them steep. Push the plastic, screened press down slowly, and voila!
Pour it into the vacuum bottle (there's a locking handle to keep your hands from burning), and share a cup with friend with the two attached cups, or keep it hot in the bottle for up 24 hours. It'll keep you warm, wired, and worked just great.
