Alpha IndustriesMen's Ma-1 Skymaster Mid Length Zip Flight Jacket with Pockets

Does this jacket have a 'no-fill' lining?

Are these authentic from Alpha Industries? They go for $150 everywhere except here they're $105.

I'm 178 cm tall and i have 72 kg. Which size should I get?

I’m 5’10 170 pounds if I wanted to wear this over a champion hoodie what size should I get ?
