Nothing moves during exercise. It is comfortable and supportive. Just what I was wanting. Thank you Knix.

I just received my new catalyst bra. I already have 3 that I bought quite a few years ago that are still going strong.
One thing with the new bra, I am very happy about is the change in straps, say the old bras very often while exercising the strap would come undone. So this is a very welcome edition. There is only one thing I was sad about, I. Loved the washbags that used to come with the catalyst bras and mine have been used so often that one is threadbare so I was hoping for another one I guess that perk is no longer accessible.

I really like the comfort of this bra. Not restricting. Only negative I have is it tends to pucker a little in the material at top edge between cups. Maybe a dart there would help.
