I now own five pair of these wonderful slacks.  They are a thin summer-weight wool with nice lining.  The fit and finish are very nice.  It is very difficult to find any wool slacks for less than $100.  These are excellent for the price.  The navy color is very dark, almost black.  The draping is wonderful without the shine of the poly-blend slacks so popular today.

Look carefully before clicking purchase to ensure these are the exact ones you want - flat front and no hidden expansion.  Also there is no cuff at the bottom of the pants leg.  Simply a straight pair of wool slacks.

Overall - I highly recommend these, especially for those who live in warmer climates.
