If there's anything I can say about the quality of the padding, it's that it definitely doesn't lose its form for a while–on top of being extremely comfy and soft compared to lower end helmets I've worn. It took a solid 2,000 miles for this helmet to finally form to the shape of my head. I would have been safe with a Medium after all, however since I prefer my helmets to be extra snug post-break-in period, I don't regret ordering a Small. Just a fair warning–as with any extra snug helmet, you'll probably get a headache after a while if you're on a road trip. Luckily, my helmet fits like a glove now and headaches are non existent. But for those first 2,000 miles…ooff. Snug as bug.
