Brand new hunting pants huh? Must of been shopping in Johnson Co...
Not trying to sound smart here but if you bought them at Goodwill had to be pretty cheap price wise, does it matter how good they are? Wear them 2-3 times on a all day hunt west of Desoto and you probably got your $$, use them as a back up pair for when you rip your Filson's on a barb wire fence.
I am actually jealous of your find, never seem to be that lucky going to Goodwill...good job.
