I just picked up the Icon vest and Knee pads.
Icon Vest: Love the feel, tight fit, it's like a cage for the body, sternum and spine protection are huge to me, coming from a mountain bike background wearing a full Dainese body armour up top (Gladiator II). This item is worn under my alpine star jacket.
Icon Knee pads: These things are strapped tight. I tried on a few different pants in the store and none of them compared to the "safe feeling" I got from these pads. The pants felt loose like the pads could be anywhere in a crash, so I opted for a pair of these bad boys. I know my ass is unprotected in a fall (until I save up for my draggin jeans), but I can live with that because the rest of my body is protected and my ass could lose a few pounds anyway.
These knee pads are beast, strong, and look cool on the outside of jeans if you want to wear em like that.(I wear mine underneath tho).
