I cannot express enough how much I love my Ol'man climber. I had a Summit and sold it. I didn't like how it packed and carried as well as not liking the seat down in the climber because it made the bar too high and interfered with shots close to the tree.
The Ol'man is quiet, easy to pack and carry, easy to use and the mesh seat is as comfortable as any I've sat in. I owned the Summit and still own a Loggy but when I climb I carry the Ol'man and loc on the Loggy.
It's not the lightest at 22 lbs but I could care less, I throw a 20 lb pack on it too.
