I've looked high and low for a pair of Small , Russell Outdoors APX or ZEPHR pants in Mossy Oak Brush pattern. Looking for new but will settle for some good used ones.
Try looking at Kings Camo. Not sure what the deal is but Russell went out of business I guess but Kings has a line of clothing that is awfully close to what Russell had. Not sure what the connection is but bought a pair of their rain pants and was pretty impressed.
