Seems to me that D30’s a great material for soft, flexible pads- elbows and knees- but not really such an asset on torso stuff where flexibility isn’t such a big deal. It’s cool stuff but not actually as effective at stopping blows as a bulky foam-and-plastic protector, which is the tradeoff of the flexibility.
I really like my IXS Hammer, which is just old-fashioned foam-and-plastic. It’s got a bulky spine protector which makes me look like a hunchback but it’s very unobtrustive on the move. Better than my old Pressure Suit (which to be fair is a pretty old model)
The POC suit is probably superb but worth it? Depends how much you wear it and how much you intend to crash I guess.
