I've always made mine from BDU pant and jacket, filling in the front side as needed for bowhunting that I had always left bare for crawling.
I did buy one a couple of years ago that I liked the look of and it is a Bushrag jacket/hood & pant. What I liked about it was that it is built on a lightweight bug suit and has the netting sewn on same as I do on my own.It's a combo ghillie/leafy type with the leaves made from sections of different colored mesh. I'll likely remove the leafy material and replace with jute because in the sun it has a sheen to it at some angles.
No matter what type you get, bear in mind that it'll be like wearing your warmest coat sitting or moving. I live in the south and I don't even bowhunt early anymore due to heat and ticks, which I have a new appreciation for. I have a close friend and avid turkey hunter who contracted "Alpha Gal" from a Lonestar Tick bite, Lyme diesease is bad but a walk in the park compared to Alpha Gal. I also spray the SHHHHH out of my suits with Permanone. Also as an aside, I wore my suit Turkey hunting quite a bit because it was my goal to kill a bird with my Shrew LB without a blind. Snakes are plentiful during turkey season and one day during a long sit, I made a fair sized Racer mad enough to hit my suit. Well...Needless to say it was on, because when a snake hits a ghillie, he sticks.
