Rev'it's SEEsmart pads are thin, flexible, and hard to notice. I have an incredibly low tolerance when it comes to invasive pads. I would rather be able to move unimpeded than have my elbows and shoulders protected with thick, stiff padding. Maybe that's stupid, but hey, we all make our own choices. Rev'it's padding is soft and subtle enough to leave in the jacket and forget about. I don't feel it on my arms when I bend my elbow, and I don't look like a linebacker with huge bulky shoulder pads, but knowing it's there gives me a little more security than the jackets which pads I remove.
