Does the job well!
After my first try at snowboarding and busting my tailbone and hips repeatedly -- I had a friend suggest pads. After reading a lot of reviews I settled on the Demon pads. These are a great fit, cover all the right spots, and after plenty of falls I had zero bruises to show for it.
They're really low profile as well and it's not hugely obvious I'm wearing anything underneath my ski pants.
