Seriously, though, carhartts double fronts are THE work pants.  They're kind of a cross between a pair of pants and a battle-armor suit.  I'm a carpenter and have been wearing carhartts for years.  I'm already a big fan.  I bought these from amazon because I can't find my size at retail stores.

FYI, carhartts fit differently than other pants.  I take a 32" waste in levis, but a 31 in Ben Davis's and a 30" in Carhartts.
