I am contemplating a nike trip to Tasmania mid to late February. for about 2 or 3 weeks. I am a little uncertain about what type of Jacket I should take. Riding from North Qld so leather is going to cook me on the way dowwn but what sort of weather shoiuld I expect on the aple isle? Riding 2 up so there isnt any room for miultiple jackets. any advice appreciated.
