Make your own AntiGravityGear Ultralight Pot Cozy in less than 30 minutes.
It's not how much you carry that counts, it's how much you don't have to carry. Cozys are lightweight and super efficient insulators which allow you to save fuel by keeping food so hot that it will continue to cook long after you have taken the pot off the stove. They weigh approximately 0.6oz/17g (BPL 500) to 1.7oz/49g (MSR 2.0L Alpine), depending on size, and will easily save their weight in fuel-not-needed on every trip over and over again.
The cozy traps the heat in so food continues to cook long after you have taken the pot off the stove and will keep it piping hot for nearly an hour.
Instructions: Place pot with hot food inside the cozy. Put pot lid and top disc in place and seal in heat by pressing top edge inward over top disc.
Here's a Tin Man from Antigravity Gear to show you how it's done:
