these are the lite version of 5.11 tactical pants.  They are lighter but they are just as tough.

These pants are very comfortable.  It is a quality product that is made to handle what you throw at it.  It fits me great.  My legs are a little bigger than most guys my size and these pants give me plenty of room.  Pockets are very convenient and there are plenty of them.  I would recommend to anyone who are going to be out and about overseas.
