I used one for a couple years about 20 years ago when I used to just climb trees. I fell while climbing and was fortunate enough to walk away so I started using climbing tree stands. It worked, not very comfortable but it was better than straddling a limb and a little safer. They used to have a small advertisement in the back of Bowhunter magazine and if you didn’t like it you got your money back. I sent it back after a couple years and they sent me a refund.
Some time after this I was at the AMO show in Indianapolis and saw the Treesuit and stood there and watched them guys asking questions for an hour. Lone Wolf was just down the isle and I ended up going with them. They were back the next year. I bought a few of the Treesuits and used one and sold the rest. I still have it and have modified it a few times. It’s now completely torn apart with plans on fixing it up a different way.
