I've got a Mach 7. I like the way it fits and the armor is much better than some of the other jackets around for the money. Most of the other summer jackets only offer soft CF armor.
One complaint...the neck closure velcro strap came off after a few rides. Easy enough to re-attach.
It's really nice in the warmer weather and the liner it warm enough that I've ridden to work on a 40 degree day without freezing my arse off.
