Although you can buy pre-made suits from army surplus stores i prefered to make my own, and heres how for only a few dollars.
Step 1: First off, why would you want to?
***Where are you going to use it?***
For me in Aus, theres only a few options, considering most of the bush (forest) looks the same. I chose the Australian military AusCam which has been specifically designed for our conditions.
Depending where you live or where u want to use it will determine the disruptive pattern you'll need.
***What for and how are you going to use it?***
There are a few options here to choose, Paintballing, Bow or Rifle Hunting, the choice is yours. The difference between these is wether you are going to be stalking somthing, buy walking or crawling. Depends if you need full-body or just your back covered.
The Common styles are:
Jacket and pants
I chose a sniping prone ghillie style, where only the back of my suit will be covered, to prevent it from catching on whatever I might be crawling over. Simply made up of a long sleeve shirt and pants.
