I was looking for a vest that was very comfortable and did not restrict arm movement at all. My friends have some older vests that I love. However, I was not any to find any newer "women's" vests that were as comfortable. I order a few and sent many back. Of the ones I tired, this is the one I liked the most. It is much more comfortable than the Kitty vest from the same company. It seems that the women's vests are made for women with very large breasts, but myself (any many of my active female friends) do not really fit into that category. The women's vests seemed to be bulky around the chest area for this reason. What I am getting at is that if you do not have a large chest, you might like a men's vest better. Always try them of because fit is VERY important.
