Could have been Mary Rose with Salamander. Was most of her stuff orange overalls and red knee pads? www.salamandercavinggear.com
Two remarks: If you have soccer-player size legs be sure the straps on the knee pads will go around your thighs/calves. Mine did not (so my slender-legged daughter inherited a great pair of knee pads).
The coveralls, while not cheap, are really nice. I love mine.
