As a hint in trimming ( I use a RS ultra light). I started taking a snip here, a snip there. I finally cut off the bow arm sleeve totally , just below the elbow. I don't need it, as long as I wear a long sleeve T shirt, which is my norm anyway while hunting. I guess a purple and fuschia shirt might clash, but camo is not all that necessary.
Inside arm of bow arm gets trimmed short, as does much of the bow side chest. Again, don't need it.
Trim the hat. RS comes with a boonie style hat, and I love it, but trim the long hangies so that they don't come over your face right at draw time.
I wear a face mask, one of the kind that is like a cut off stocking that slides over my head, but has no top. That goes over my face and nose. Also helps keep skeeters at bay.
Gloves are a no brainer. There are some on the market that are ghillie like. Frankly, I don't like them because of all the stuff in my "aim picture". Trim trim trim.
Problems with a ghillie ? They could be warm ( mine is the ultra light and not so bad). They get stuck on everything if you are sneaking. The animals COULD get too close for you to draw. They could get addicting. I have also had close encounters, from birds landing on me to mice and chipmunks walking over my feet, to a skwerl using me as the tree etc.
