With all camo, consider how conspicuous you look,
either on the way to the trail-head or even on the
trail. People may go out of their way to snoop into
what you are doing or to relay info (gossip) on what
they saw.

If you must wear camo pants, wear a bright shirt.
Solid colored BDU pants are not noticed much because
cargo pants have been a style for about 8 years in
the US.

Plaid shirts are better than camo shirts, because
when people do see you, they think nothing of it.
When trying to avoid being seen, in the bush, plaid
can work almost as good as camo, sometimes better.
