Laminated membrane motorcycle jackets are the best option for high mileage daily commuters or big distance tourers. A laminated jacket is where the membrane is basically heat sealed to the inside of the outer fabric of the jacket. This makes the jacket inpenetrable to water. It will never wet out; it will dry quickly and where there are vents they will allow air direct to the body for most effective venting. The very top of the tree for a laminated jacket in the motorcycling arena is a 3 layer Goretex Pro membrane which we stock from companies such as Klim, Rukka, Stadler, Belstaff and more recently even Richa.
