This version of the classic MA-1 flight jacket is perfect for warm temperatures. While the original MA-1 was designed to protect pilots from harsh conditions in cold climates, the TT model is intended to provide the opposite: the lightweight nylon construction and lack of padding promote breathability, while maintaining the superior quality and versatility expected from Alpha. The MA-1 TT is similar to the MA-1 in terms of appearance (it also features the iconic RBF Tag on the left sleeve) but actually has a slimmer cut for a closer fit. As a summer jacket, it is designed to leave room for a shirt. As a result, the MA-1 TT is a great companion for mild summer nights. -Outer material: 2Tone Nylon -Fit: Slim -Lightweight jacket.
