The Med. Ribtect was too small for me in the side and rib areas. It was tight enough to effect my breathing, I felt like I could not take a deep breath. This was with my vest on. The legs and the hips were good.
The ML seat I have clears my arm pits good. It was a little loose on the sides and rib area until I added the padding. The Zoombang pads are about 3/8 thick, with them the sides and ribs are snug. There is a little room for movement in the leg and hip area but it does not bother me. I could probably add some pads to the sides of the legs. I still have the Med seat if you are interested, I think it is probably too small. Where are you located? I am about an hour north of the Jim Hall school.
