Buffalo gave the Siena a tough 600 Denier polyester outer, with a waterproof, windproof and breathable drop lining and removable 120 gram thermal quilted liner. Zipped ventilation to chest, upper arms and back help to regulate temperature. There’s CE-approved armour to the shoulders and elbows, with a pocket provided for back armour, as well as two generous external pockets, with hand-warmer linings.

Fit is taken care of with elasticated panels to the sides at the base of the jacket, which gives a close yet comfortable fit and is enhanced by additional zipped darts at the base and an adjustable twin belt system to the elasticated waist. An internal 8-inch zipper allows the Siena to be attached to Buffalo jeans.
