I've used a leafy camo suit for maybe 20 years. It's not any common camo pattern but has worked exceptionally well. I've had birds within 5 yards not notice me.
I think the key is the cut pattern, not necessarily the camo pattern. I had to wash mine several time to eliminate the "swishing" sound when I walked. I did that with cold water, no detergent, and a cool drying cycle.
My suit has held up exceptionally well over the years and still works as well as it did when it was new.
Thanks,
Clark
