I have recently logged 6000 miles using the Nolan N43 Trilogy. Mountain peaks to desert to everything in between. Rain, fog, high winds and temps from 104 to low 40's. Conclusion: rates a solid 10. Bought it from J&M with their mike & earphones installed (10 % CVO discount) . Love the flexability of full face shield, or open with chin bar, or 3/4 open with removable visor and the neat internal flip down sun shield. The full face arrangement with the added "pinlock" second inner shield (not included, $25 additional), provided the best fog free, rainy weather performance I've ever experienced. I think my new 7" Freedomshield windshield also helped in diverting a lot of the rain away from the helmet.
Helmet is lightweight, well ventilated and has no blind spots when looking to the rear. It's a keeper. Just ordered one for my wife.
