Last weekend I spent two nights in my DIY Bridge. I was just a little cold the first night at 40 degrees or so. Since a bridge is narrower than a normal hammock and underquilt, I noticed the air getting in near the center between the bridge and the quilt. My buddy, Dave gave me a tip and I wanted to share it with you.
Out in the woods, I used safety pins, but then made the mods on all my underquilts after I got back by sewing loops on the edges.
Out on the trail I simply took two 18 inch lengths of 1/8 bungee and tied a loop in each end making them about 14 inches loop to loop and pinned them to each side on the edge of the underquilt about 10 or 12 inches apart and centered lengthwise on each side of the quilt. Then after getting into the bridge and pulling my overquilt over me, I pinned the two lengths of bungee together over the center, making an X over my body. This small amount of force pulled the underquilt in to hold it very snug to the hammock. I had a wonderfully warmer night that night. This works well.
One of the pictures shows the reusable velcro ties I am beginning to use instead of mini biners. I will use these to close the two lengths of bungee into an X to hold the sides closed. Mule
