@DB4x4, I don't see those straps for 2.99. I see them for 9.99.I bought a set of super cheap hammock straps from Amazon. One end has a single sewn loop, while the other end has a series of sewn loops for adjustable hammock attachment. I cut the strap around the mid point where the series of sewn loops starts.
I girth hitched the single sewn loop strap to the platform on one side and used a 1" tri-glide on the free end to create a fully adjustable loop on the other side of the platform.
I use the other half of the strap with the series of sewn loops as a pack/gear hanger on the tree. Not bad for $3, huh?
