Catalyst Sports Bra

I now have four of the catalyst sports bras, as someone who has struggled to find an everyday bra that supports and feels comfortable I can not express how happy I was to find one that fit those boxes and was not over $200. This product is quality right from the way it is made, affordable price, fit and feel!

Best sports bra

Bra was a little tight the first wear as expected so I wore it for a couple hours prior to wearing it for my kickboxing class and by that time it get better and now after wearing it 5 times it fits perfectly, secure but also like I am not wearing anything. Highly recommend!

Love it!

It was so tight when I got it that I actually had to wiggle it on over my head for my first run. So I'll admit I was a little nervous, but I remembered this from my first panties I ordered too. They fit very snug, too snug at first and then they relaxed into a more comfortable and flattering fit. I have to say, the same is true for the bra. I absolutely love it. It's supportive and holds everything in during any kind if workout. It's super comfortable, I'll definitely be ordering another one soon!
