Does anyone own a gear hammock? I've been trying to perfect my hammock setup and I'm still not 100% happy with having to place my backpack on the ground or hanging it from a tree. I feel like a gear hammock like the "ENO Underbelly" would be the solution. However, I never see any hammock campers use a gear hammock....I'm I missing something? Just wonder if anyone owns one and what the pros and cons are.
