I was reading this old post after inspecting my small diameter friction savers to see how they are doing. I have a question that was not answered in the previous postings.

Is the material used by Elliot the same as the one used by Treetramp?

My two sleves made by Treetramp are in perfect condition after one year of use. The only thing that I have done is replace the tape covering the end caps but the material appears in good shape. FYI: I never drop the sleve from the tree since it is always lowered by riding the rope down and then I remove the rest of the rope from the TIP. I do not know if that makes a difference from what others climbers are doing or if the problem Moss described is related to the material that Elliot used (that appears to me to be different to the one used by Treetramp.)

I hope either one of them will post something or contact me by private message if they prefer that way.
