I've been riding with a Shoei RF1000 for about a year. I wanted something in a lighter color and with more vents as I live in Georgia.
The GM68 is a very good helmet. The fit is a little small, but more comfortable than my Shoei for a long ride. It is definitely louder than the Shoei, but it has a ton more vents, so you'd expect this.
My only disappointment is the tinted shield, which is not as dark as the Shoei's. Bright sun really requires sun glasses, which is a problem for me as I wear glasses.
Overall this is a very good helmet at a very good price.
Waterproof liner zips into Phoenix 3.0 jacket, Reactor jacket, and Reactor S jacket Can be worn underneath any jacket Shell is breathable, waterproof membrane Torso lined with fleece Elastic cuff and waist Available in Men's sizes S-5XL
I bought this liner to convert my textile jacket to a fall/winter riding jacket. It does a GREAT job! Fit is good and on cool mornings it keeps you warm.
