My favorite patterns in no particular order:
Predator Fall Grey
Mossy Oak Brush
King's Snow Shadow
Open patterns, with large splotches that break up my outline. NO dark camo. Most camo turns into a black blob if you step 100yds away from it.
Then I camo EVERYTHING. My face, hands, guns, and gear. The more blended I am, the more movement I can get away with. The more movement I can get away with, the more dogs I can get a clean shot on.
Also, the garment itself is very important. I want water resistant/warm gear in the winter and fall, and breathable light gear in the spring/summer.
As for quality of garment when coyote hunting, the kings parka/bib combo is the best I've worn so far.
