Gil,
I have a Rancho Safari ghillie suit, and think it is the best "wearable blind" you can get.
I have the short jacket, pants and boonie hat. I have hunted just about everything in Oklahoma successfully with it. I suppose it is the "light" version. It doesn't weigh any more than a medium weight jacket with all three parts bundled up. It’s made completely from strips of camo cloth. It isn't heavy and will not soak up water in the rain. Lots of folks recommend the long-coat. From what I have read it goes down to your knees or so. My short jacket falls just below my waist after covering my "more than ample" mid-section.
If you are going to be sitting on a stool or the like when you hunt with it, I think the long-coat might be best. I really like having the versatility of jacket and pants. I even use the jacket while wearing waders, duck hunting. If I am spot and stalk hunting for feral hogs I will wear just the hat and jacket so I can move quick. In the early part of the year (October) when the trees still have their full load of leaves, I use it in tree stands (wearing the pants, jacket and hat). I always wear a face mask of some sort and gloves. Total coverage.
I also definitely recommend the hat over the hood, more versatile and easier to use with a bow. The hat turns with your head rather than the hood staying put and your head turning inside it. Mine needed a little trimming so my draw and anchor weren’t obstructed. I sewed in a snap just over my right eye so I could snap the hat brim up to shoot.
The VERY FIRST thing I think you should do is put it on and shoot your bow. It is my experience that the sleeve of your bow arm will need to be trimmed up to eliminate string interference.
They are a lot of fun to hunt in. Here is a picture of my niece wearing mine for a really intense game of hide and seek.
Have fun! Holler if you have any other questions.
