Mammut Motion Pro Shell Jacket

Has anyone tried this jacket? I have been looking for a lighter weight 3 ply Gortex for winter/snow trips overnight and looked at one of these at Mountain designs. It weighs about 510gms. I found it comfortable in shop and liked it but can't find any reviews of it. MD have it on sale at $562! (Down from RRP $$750!). I can get it from USA on line for US$240! + freight approx US$80 - ie about A$337 all up! Love to hear from anyone with experience of this one?http://www.espacemontagne.com%20is%20one%20site%20that%20shows%20the%20jacket%20and%20specs
