Ghillie suit

For anyone else who has to look it up like me...

A ghillie suit (sometimes called a yowie suit by the Australian Army) is a type of camouflage clothing designed to resemble heavy foliage. Typically, it is a net or cloth garment covered in loose strips of burlap, cloth or twine, sometimes made to look like leaves and twigs, and optionally augmented with scraps of foliage from the area.

Snipers, hunters and nature photographers may wear a ghillie suit to blend into their surroundings and conceal themselves from enemies or targets.
