Prana Stretch Zion Pants, Men's 31W X 32L, Color Cargo Green.  This is the original Stretch Zion, known to be much more robust than the newer Stretch Zion II (which is made with recycled material and people complain that it gets ripped up too easily).  

Great condition, worn on occasion for hiking and climbing.  Trading these to get more obnoxiously bright colored pants.  

Shipping $6.
