Finding the Hennessy too claustrophobic I now use a GT Nano 7. As I already have a lightweight down sleeping bag I intend to use this as a top quilt with the 3/4 zip unzipped to leave a foot pocket. However, I am worried that the Nano 7 is a little delicate and I was thinking of shielding the zip pulls with velco tape to prevent them from puncturing the hammock. But what about the sharp teeth of the open zip itself, could that damage the hammock? Does anybody with a Nano 7 or similar have the same worries?
