I own a treesuit, after trying out a friend' s, I was convinced that it may be a good way to make myself more mobile. One of the things that I really like about it is that it sets up quickly and fairly quietly. Also, the built-in harness system keeps a person safe while climbing the tree. The shooting positions really are endless. Facing the tree makes it a little easier to stay warm on those cold days.
One of the weaknesses is that there is some extra strain on the body in certain positions. Another weakness is that there is more stuff to carry in when hunting. However, I have found that having the treesuit to get out and try a spot a couple of times before I choose to put one of my few fixed stands there has been a bonus.
I do not own a climbing stand and I haven' t purchased treesuit' s climbing platform. I just use a climbing stick and a couple of tree steps. IMO, the climbing platform, would greatly improve the experience.

Jeramy K, I weigh about 265 pounds and I do ok, but sometimes when manuevering I wish I was smaller
