I've been thinking of picking one up both for commuting and for doing some long distance events where one will be required. I'm curious whether others use a reflective vest and what do they use.

I'm leaning (very so slightly) to getting this Amphipod Xinglet, Amphipod Xinglet? - independently top-rated for visibility and overall usability.

It won't be hot in the summer and it can fit over bulky winter clothes as well so it looks pretty versatile.
