As the warmer season draws nearer, I'm more often thinking about my bug net needs. I've been shopping around a bit, and was certain that I was going to get the Fronkey style from Dutch. Problem being, I really would rather have a zipper over the bottom entry of the fronkey. I have a 10.5' hammock and a 11'. I know 2qzq makes an extension, but my question is, do I really need the extension for a 10.5' hammock? It's my go-to hammock these days.
