I purchased a Hyperwear Pro weighted vest in 2012. I decided on this vest because of Margaret Martin's review.

However, I stopped wearing the vest because I began to read conflicting information about using a weighted vest.
One of the concerns was that the vest can cause a forward flexion of the back which isn't good for osteoporosis. Recently, I had an appointment with a Mayo Clinic Endocrinologist and he said I could wear one. His answer surprised me because of my severe osteoporosis. My L1 & L2 T-scores are both -4.5. I am going to look into this further and maybe start with very low weights again.
