At Caterpillar, we believe having a work pant that is durable, high-performing, comfortable and breathable is just as important as having a solid set of tools. The Caterpillar Men's Trademark Trousers are made from our special C2X 60% cotton/40% polyester canvas fabric. These work pants have a scuff guard and bottom hem trim made from 900 denier polyester to ensure longevity, along with a 20 in. leg opening that should fit over any boot. The top loading knee pad pocket has the same 900 denier polyester, double layered, to increase performance in this critical area. Bending and squatting during the day is tough on the knees and circulation behind the knee, but with CAT's Articulated Knee, the fabric bulge at the back of the knee is reduced to help maintain circulation. Have you ever found yourself looking for just one more pocket? With a total of 21 pockets you can find a space for everything you need. The Caterpillar Trademark Trousers are truly heavy-duty work pants that are hard to beat at any price and ones you will be proud to own.
