I just recently joined on here and on the FB ground SH Nation to see if there's anyone else out there still using a Treesuit like I do. I've been using mine consistently for about 20yrs now and still love it, have taken many animals from it including most recently my first bear this month. I still love how comfortable and simple it is. I'm tempted to try a new saddle, but nothing looks as comfortable as the Treesuit honestly. And even though the new stuff is safer in certain ways I'm amazed how many people only hunt their saddles as single point of failure systems with no safety... Even my 20yr old Treesuit has a secondary safety strap that I always use. And after 20 yrs of using it I would never use a system with only one point of failure for sure.
One thing to be aware of is that at some point Treesuit sent out a redesigned D ring strap with doubled material, the original one had exposed stitching which could wear over time on the tree bark. It's nothing I would be that worried about using, but just something to be aware of and keep inspecting if you still have the original d-ring strap.
Only one time in 20yr have I ever slightly scared myself with the Treesuit, and that was when I inadvertently threaded the main strap through the wrong part of the buckle when getting set up in the dark. Even so it held until I noticed it in daylight, and had it not I still had the secondary safety strap on.
