Elisa D.wrote a review of Pearl Izumi Flash Insulator Jacket - Women's on February 10, 2017
Familiarity: I've used it once or twice and have initial impressions
I've been using some cycling clothes, especially winter clothing, for running, because running clothes seem to lack in pockets and insulated materials in general. I had first bought a large, based on reviews that it ran small. I usually wear a small/medium but I wanted to add multiple layers underneath. The large was just too long and too wide. I then bought the medium. It fits well--I can add layers and the lengths of sleeves and bottom are longer but not too long. The hand pockets are great. It is also highly visible, especially with the mix of colors (although it wouldn't win an award for best visual design). I've worn it once and was very happy with it. I don't think I'd want a small, so it may run a little small, but not that much. Thus, I'm putting true to size.
