I have the radar 2 piece... and the only complaints i have are the ones he mentioned.I just bought a Radar 1 piece 2 weeks ago. Build is nice. The only negative I cansay so far is the liner is permanently sewn to the suit so you cant wash it. Ventilation is good. Armor is good. Fit is good if you are built stocky. The fitment guide on NE is pretty accurate.
The zipper on the 2 piece only goes 75-80% around. I didnt like the 2 piece nearly as much. It also doesnt have the aero-hump the 1 piece has. Other than that, quality is the same as the 1 piece.
If you decide to buy one, you can get one for under $400 shipped from motoxoutlet.com. Just enter "sale" in the coupon code at checkout and it will knock $132 off the price listed.
I would have bought a TILT custom suit but the lead time was outside the window for when I needed to have the suit.
