I have been using Scottevest for years. I have this vest also. I find it great for going through the airport security lines. My pockets can be full of items I might normally carry in my personal bag and it doesn't count against me. I can either wear it or hang in on the hook on the back of airplane seat and have everything easily accessible during the flight. I also use the cord management system to keep my earbuds handy. It is also a great layering item on vacation and keeps your items from pickpockets.
Have you used this vest in warm, humid climates? I know that Scotte has the Featherweight model but this model may work better for me. I am 5'3" tall which may or may not make a difference. Thanx for any input
