The MSR TRANS JAK is a transformable rally style jacket/vest combination that is designed to let you move freely and yet control the body comfort and temperature level of even the most aggressive riders.
420 Denier nylon Oxford body with heavy duty nylon in the elbows and should area.
Heavy Polyurethane coating keeps the fabric water resistant.
Zippered vents in front and back, four front pockets, and two internal pockets give you more than enough storage.
Fleeced lined hand pockets with internal shock cord adjusters.
A vented rear pouch on the upper back holds the sleeves when not in use and a lower back pocket offers even more storage.
Internal pockets on the sleeves of the mesh lining accept an option pair of elbow guard.
Designed with extra room to be worn over a roost deflector.
Fabric is not as heavy as my 4yr old jacket, still durable though. Sized on the small side, I ordered an XL now I can wear a layer under and it fits great. Still good design with vents, pockets, zip off sleeves that store in the back.
