Unless there is a simple, expedient method, I'm just going to zip myself up and put duct tape over the zipper of my sleeping bag. Last night, I woke up to find teeny tiny tears (more like dents) in my hammock from my sleeping bag zipper.

What can I do to use my sleeping bag but protect my hammock as well?

Thanks and I hope you guys cut my newbie-azz some slack for my silly questions.
