Ambec Portable Hammock Tree Straps System ,Heavy Duty Extra Long Lightweight Suspension Kit ,Adjustable Extra Long Heavy-duty but Lightweight Extra Strong Durable Hammock Straps The greatest feature is the locking mechanism on the locking bolts on the carabiners.With this feature,there is no chance of the carabiners accidentally coming undone while people are in the hammock, or it being blown off by the wind when no one is in it/ when away from the camping area.You will not have any issues with stretching. The ease of setup and ability to adjust the straps to any size tree makes setting up the hammock much easier and faster.You can got up from the hammock and sat down many times and swung on it too, and the straps did not move or slide down. The length gives you more then enough to use on larger trees and set the straps high enough to keep the hammock well above ground but still leave enough slack for it hang properly for comfort. The stitching on the straps is very good and each loop is triple stitched.All the seams are sewn very tightly and with a heavy nylon thread. The loops are just right for adjusting to tree size and attaching the hammock,wide enough that they don't harm the trees.
