If you have an aversion for makeup, slip on a mesh or cutout facemask. Mesh masks are colored with a faint camouflage pattern that you can peer right through. Cutout masks are just that, a fabric or foam cover with cutouts for your eyes, nose, and mouth. Nothing looks more out of place than a pale human face beaming from behind a properly designed blind. An effective, but inexpensive way to outfit your self with camouflage is to purchase a patterned, waterproof outer shell.
Numerous manufacturers produce camouflage raingear.
Use of a camouflage rain suit enables you to wear as much, or as little, cold weather clothing underneath without spending hundred of dollars on a cold weather, waterproof outfit. Avoid stiff outer fabrics. Rigid plastic rain suits can produce unwanted noise. If you can afford it, high grade, multiple piece, waterfowl parka and pant sets are pretty awesome. A blind has two functions.
