As I mentioned on the Winter forum, I've worn that jacket for 4 years (~10K mi). The seams are sealed so it's waterproof/windproof but paper thin. So you'll need to layer for cold weather. In hard rain, remember to layer, cuz that rain hurts

When comparing mine to a new jacket some of the yellow has faded slightly. But the reflectivity has not diminished at all. Reflectivity on the arms and back seem very good.

However: At night, riding on the drops, that back reflective stripe is NOT visibile.

Edited: If you do rain and snow, get the hood, it's thin and keeps your head and neck very dry without hampering visability.
