When you say ' how do you use them'...I think this is the reply you want

Perth weather's been like yours lately & often I just get wet. I no longer care about riding in the rain & just go out with some sort of rain jacket. If it's a bit cool, arm warmers & a vest. In the late morning when I venture home, throw them in my pocket.

Summer is around the corner but lately the weather's been pretty annoying & unpredictable. I'm tired of the sand on my bike & the crazy winds.

In a few month's time i'll be complaining (with Trekhawk) about the heat.
