This is the Jumbo Shrimp of Packable, Portable Bags

These bags from ZeroPoint are small. Possibly the smallest “micro-bags” in the world. They pack down to a size that’s roughly the diameter of a quarter & about an inch thick. Once unfurled, they expand to 12 X 16 or 8.6 X 12-inch sizes and are strong enough to carry your laptop or a load of items from the supermarket. A funded Kickstarter.
