These pants are awesome. They protect your legs very well for welding. If you use your knees for low level welding, brick work, tiling, carpets or roofing, your knees will wear out before these pants do.

positive

Ex Input:
Plastic button covers the on/off button. You have a hell of a time turning this on and off then at random (not even trying to turn on or off) the turn off screen pops up. I've ordered many Snugg cases but this one truly sucks. Where the pen holder is - is where the strap to hold it close is. If you put a pen in the holder the close flap keeps popping open.

Ex Output:
negative
