Check your gear out before you head out.
Just returned from a hammock camp with some friends and my daughter. One friend had bought an ENO bug net the previous day and headed out without checking it at all. After an hour and a half drive, we arrived, checked out the area and started to set up. All of a sudden, Dan says his ENO Guardian has no zipper.
A minute later, Dan again announces that his bug net has no zipper and asks if someone will double check in case he is missing something. Well, he was. The Guardian had a zipper, but the zipper had no pull tabs. I mean there was NO way of opening it.
Extremely upset, he packed up his kit and returned home to get the net replaced, but he didn't return. So even if you don't do a backyard test of new equipment, at least open it up and make sure it has all the necessary parts.
