I just got an email from Scottevest that they have some women's and men's vests online for sale $50.00
I travel with one to Europe, we go in late fall, so it's cool to cold. They don't look like fishing vests and they are lightweight. The trick is to not FILL UP every pocket! I use it for my phone which is my camera, sunglasses, small meds case, chapstick, and I use one pocket for papers that I need for reservations for tours and whatnot. I also wear a neck wallet for deep storage, but if the vest is zipped up and the inside pocket is zipped, sounds pretty safe to me.
This frees me from carrying a purse. I was having neck problems and my Dr. told me to quit carrying a purse that was loaded. The other advantage is, I take it off at Security in airports and put it through the X-ray and everything is contained.
If it works for you that's great. If it doesn't that's ok, too, just realize the email says "All Sales Final, No Exchanges or Refunds" I'm going to buy one in another color.
