Zerobag - An awesome NZ made alternative to the plastic shopping bag

Has anyone stumbled across Zerobag bags yet? They're made here, from recycled parachutes soucred locally. When I heard that I thought 'why would I want a bag made of parachute?' I had assumed that parachute material would be big and bulky but no, it's really thin but also super strong. When the Zerobag team told me that the bags would hold 16 bottles of wine I thought they were having a laugh so I tried to catch them out. I didn't have that many bottles so raided the book shelf, filled the bag right up with books and it survived, I should have just believed them to begin with! Not only are they super strong, they pack down so small that I usually have to hunt through my handbag to find it.
