I really like my vest but I need more inserts so I can go out all day to a theme park. I looked over on the Steele web site and it gives me all these different pacs I can order. which ones do I want for my vest. How long does it take to get them and should I order two sets? Any ideas besides the obvious of taking a cooler along to keep those frozen so I can refresh my vest throughout the day? Oh, so many questions. It's the heat. My brain is fried in this midwest. if only we would get some rain. If any one knows a rain dance and has the energy to do one, we sure would appreciate it!
