I realized I was ruining my expensive bras as I sweated (yes, I sweat) on long walks and bicycle rides in this sunny, warm climate.
I came to Amazon, of course, to find a sports bra that is cool, comfortable, and not a racerback.  My sister, who is a miniature of me, always recommends front closure sports bras.  So, I was looking for that feature too.

This bra is just what I wanted.  It's easy to put on--you don't need to unhook the hooks ever.  Just pull it over your head and adjust.
It is comfortable, cool, and gives support.  It's also at such a good price I don't worry about ruining it with perspiration.

The only thing downside is that I think it flattens me a bit.  I sort of expected that and it isn't a big deal.

I bought three gray ones, but am thinking of getting a couple of other colors.
