The one pack is UL under twenty pounds so I s clip it to the strap after getting the hammock up. or a short piece of cord what ever is handy - just off the tree and in a way that when I get in it doesn't slide towards me. - The benefit is that its right there at eye level when you get out of the Hennessy. With a S clip you can move it under the tarp in the rain to keep it dry - hense I never need a pack cover. I use a Kitchen garbage bag on the inside, just in case the water bladder fails or gets a hole and the down bag is inside a waterproof sil nylon bag...
