Update on the Tru-spec pants from Amazon:
I took them out on a 10 mile hike both on and off trail and they performed very well. The fit is REALLY great thanks to the well-done elastic waist that just stretches as you put them on and then pulls back in to be nicely snug once everything is in place. I can see how some people claim these to be the most comfortable pants of this type. They provided the right amount of protection against the 40-50 degree temps I walked around in and they shrugged off the snow and drizzle I got, too. For build quality in a $34 pair of pants I'm somewhat impressed although there were a few loose threads here and there.
All in all this would be what I am looking for except for a few niggling details:
1) I wish it had more zippered pockets instead of the heavy duty velcro closures. They cannot be opened without getting fairly loud.
2) Speaking of noise, the pants definitely aren't very quiet. The fabric tends to "swoosh" a bit as you walk. It isn't quite loud, but it was noticeable at first. However, during my 10 mile hike I never noticed it much.
I will continue to try them and maybe even buy another pair if I don't try out some of the other options. The jury's still out on whether I would want to hunt up close with them, but they would certainly do well for a longer rifle hunt and are really great for hiking.
