Made from Bailo's Gore-Tex Skudo Anti Tear Material with an adjustable insulation system.
Basically you blow on the tube in the front pocket and the inner inflates/deflates so you can adapt to changing conditions without the need to add or remove garment layers.
I said I'd never sell this jacket but it's not too big for me at 24" p2p (tagged as a large).
No issues whatsoever the thing is practically indestructable.
Detachable hood, 4 front outer pockets and two rear poachers.
