Lots of good hype - Patagonia Nano-Air Light Hybrid Vest - Women's

I read the reviews of this vest before I purchased it, and I was so excited to find it at a good price. However, the fit is just OFF. I take a small in Patagonia - always - and the small fit me in the length and the chest, but was just too dang baggy in the back and along the sides. Maybe that's how Patagonia designed it so that it would breathe, but the description says "athletic fit", and it wasn't. Was positive I could use this for skate skiing and other aerobic activities, but it just didn't fit the way I wanted it to so I sent it back.
