The new 2181 ULTRA Workpants just released by JOBMAN Workwear are possibly the world's best workpants. Ultra durable, comfortable, and functional, these pants have it all. New on these pants - Kevlar in the knees. The fabric over the knees is a special blend of polyester, Kevlar, and spandex, which makes for very durable kneepads with the ability to stretch and be anti-slip. Also, in the knees are bi-level internal pockets so you can position your kneepads to fit your body style. These pants also have a pocket for large smartphones, a zippered thigh pocket, and separate pockets to hide the tool pockets into when not in use. This is a great pair of pants.
