Well did a search and just found 1 topic (real old) on this and it was asking about them but no reply, so I'll start it
Just bought one, looks like this but different colors being last years model
It is real comfortable, real good padding with plastic sewn into it and foam. It is basicly a chest-spine-elbow-pads with a built in kidney belt. It is a little heavy but not to bad. I will be a little hot in the summer but so is most pads. Overall I like it but would not spend the 175 msrp. I got it new on ebay for 50. I'd say worth 100ish if you race and need good pads. It has lots of adjustments to fit it just right on. Only complaint I have is it don't fit tall people (I'm 6'5") real well, but not much does. Wish the big and tall store sold race gear It goes under the jersey and is all mesh so should vent well when moving.
