Armor for the legs!!  Utility that lasts and lasts, tires out the energizer bunny!!  20+yrs in the construction industry, these save me money over blue jeans!  They are cool on hot days, hot on cool days......they breath well and protect me from welding arc burns, plasma arc, oxy-fuel ambers and the wayward cutoff wheel......save the knees from grate, ruff concrete and overall are all I wear!  5 pair last me 4-5yrs!  Du....th Trading Cargo's lasted me about 2.5-3yrs....... I started with these 15yrs ago, switched to DT's Cargo's & I've returned!  Hands down if you want safety, quality, protection, utility, durability, and savings........downsize you're wardrobe and save the time trying to find jeans without holes than look professional and outfit yourself like a pro and invest in you, buy five pair & do you're laundry on the weekend!
