Required in NYS?
Unless I missed a change in regs - It is strongly encouraged but not required in NY. Personally the family all wears it now but grew up with just Hunter plaid.
I do prefere a blaze orange camo pattern to break up the silouette. NJ requires 200 square inches visible from all sides a hat alone does qualify. Always wear it moving but when sitting I'll sometimes take it off to avoid attention from hikers and dog walkers.
