Definitely more than enough padding in these shorts. Tailbone saver! I'm 5'8, 155-160lbs, and waist 32. I bought a medium and they fit fine. A little bulky but that's expected. I usually wear medium Burton or Northface snowboard pants, and these shorts make my pants a little snug, but they work.
Only con... the material that holds the padding in place stretches out while wearing em. So the small hole that you insert the tailbone foam pad into, scretches and widens. The tailbone padding comes out and rides up your back. A little annoying on the mountain. I was able to fix this by sewing the hole smaller, and the tailbone pad no longer comes out.
So again, shorts provide good protection, But the materials used aren't the best out there. I got these on sale and fairly cheap, so no complaints.
