The Tracer features a unique double face stretch fabric made on a special knitting machine. The internal polyester brushed construction keeps you warm and dry, while the external Merino wool blend face provides an efficient, natural moisture management system. Sleekly structured and durable, our strategically placed nylon reinforcements were inspired from the samurai’s impressive winged shoulders and massive overvest and act as additional protection. Behind each level, much like the original layers that built their suits, we integrated concealed, secure pockets behind the front hand pockets and bicep pockets.
