I tried one on the other day.
I liked it very much,all except for the stupid poppers that hold the lining in the sleeves.
Took me ages to do up/undo,as the elasticated cuffs make the poppers very difficult to reach.I reckon they would last a few weeks,tops,if you were constantly taking the lining in and out (as we did on our trip a few weeks back).
Think I'll stick to Dainese,and probably go for the new Goretex Neck,when I replace my current jacket.
