I'm going to mention NaturalGear with a caveat.
Not only have I found it to be a great pattern for deer, but more than one time on stand I've had a bird of prey perch within feet of me totally unaware of my presence until I moved!
The caveat: their product line seems to have random availability & I feel the quality could be a bit higher, though for the price it is fair.
ASAT-my friend & I learned about this several years ago now & he rec'd a few garments at Christmas. We did a comparison test. I understand deer "see" differently but, we were both able to pick out the ASAT much easier than the NatGear pattern in various backgrounds(including different seasons)-and he is color blind!
I do think ASAT is good quality & have had their Elite line on my wish list for awhile. The thing is, I've harvested far more deer than my buddy has!
I once had my photo taken, at a distance, wearing Mossy Oak & Real Tree 3d-I may as well have been dressed in hot pink- just one big human shaped blob.
To be honest,the old style Forest Green always worked for me & I've talked with guys who swear by the newer digital camo versions as they are readily available and fairly inexpensive!
