From their website:
Ten C is designed by Alessandro Pungetti and Paul Harvey and is made exclusively in Italy. One fabric. Four colours. Seven jackets. Forever.
I understand that the designers have put time in at C.P. Company and Stone Island.
I just picked up their field jacket and it's a serious piece of outerwear. This is not a fashion jacket. It's functional and utilitarian and the aesthetic is straight-up army surplus. The cut is a bit on the boxy side and the construction and hardware are solid. Every review I've read emphasizes the fabric and I can definitely understand why. The first word that comes to mind is "industrial". The jacket practically stands up on its own. It's soft to the touch but also very rigid and is apparently both breathable and waterproof, though I haven't tested it yet.
They also make removable liners that work in all of their jackets, which seems pretty practical.
