I am part of an affiliate program as part of ShareASale which is okay. It is no work for me at all.
I looked at your web site and the description of the product that you have been developing. I think it is a great idea but I had a very different thought from the one that you have brought forward. I was thinking of people with MS. Overheating is one of the greatest problems, and the summer month, even without exercise, can be very challenging. I can imagine that your vest can help there as well.
