Just like with bows, arrow shaft materials and broadheads. We all have our favorites. I find that ASAT, followed closely by Predator grey or brown are extremely effective for me in all hunting environments. Animals seem to look thru me even at close distances whether hunting on or off the ground. These patterns looks horrible when I look down at myself when wearing such "open" patterns with a lighter color as the background, or with a lighter color liberally prevalent within the pattern. However, such patterns have been extremely helpful to me over the darker patterns I wore in years past. Whether hunting in low light, last light, in the shadows, or mid day, I love these patterns. I have been told by other hunters and hunting buddies how effective these patterns are in breaking up my outline and concealing me, and how they have been unable to pinpoint me on stand. ASAT is my preferred pattern if I had to be restricted to just one pattern for all my hunting needs. Most hunters would not consider using the ASAT pattern because of the light color within the pattern. ASAT is more muted in it's coloration in wool as compared to fleece, cotton, or any of the modern water/burr resistant materials (like Day One Camo's Buck Suede, Cowboy Suede, etc.).
