Better than a faux-Ferrari polo made of a cheap polyester, the real grease monkey in your life could get a lot of miles out of a pair of good coveralls. We can definitely recommend any of the Dickies line of coveralls, as they offer comfort, durability and value. Murilee manages to burn through a pair of these every couple of months. It's the best way to protect your nuts and bolts during repairs.
The prices range from a little over $30.00 for the basic cotton/poly short-sleeve coveralls all the way up to around $64.00 for the fully insulated, water-repellent version. We'll take ours in brown with a "Gordon Liddy" nameplate. [Dickies]
