Must own!

This is, by far, the best sports bra ever made. I own 6 of them and they are all I ever wear. My sister borrowed one for hot yoga one day and even asked for it for her birthday present. Love

Comfy; will probably buy more

So far, so good. I am a long-distance runner who is extremely picky about sports bras. I want a seamless, pull-on compression bra that wicks well, doesn’t chafe, and is supportive enough that I don’t even think about my bra while running because nothing is bouncing and no fabric is sliding. I had a go-to brand that I used for 35 years, but recently the company stopped making that type of sports bra and I had to go look for a replacement. The Zensah Seamless Running Sports bra is the best replacement I have found so far. It is super comfortable. It wicks like a champ…though like all wicking material, it worked great while I was moving, but was a soggy mess as soon as I stopped. Not that that earns demerits, because they’re all like that, but the Zensah has a somewhat puckered, layered design that seems to hold sweat like a sponge. It’s not a deal-breaker, but I definitely noticed it. There was no hint of chafing whatsoever over a two-hour run; I feel pretty confident about using it for longer distances. The fabric is stretchier than my previous favorite bras: the good side is that it’s a little easier to pull on and off because of the give in the fabric; it also stays put beautifully because of the springy compression. It feels a little less compressive and tight than I am used to, but it was perfectly supportive and it passed the “I didn’t think about my bra at all once I started moving” test. I am still looking at and evaluating sports bras from several other companies, but so far, Zensah is the one I like best. Excellent performance and excellent value for the price. I would like it even better if it were just a skosh more compressive, though.

Best sports bra ever

Amazing. Perfect. Enhanced my running. Elongated my time. I bought another immediately.

Just OK

I was surprised at the amount of bounce, especially since it's so highly recommended by women runners. It's very comfy, but not the support I was looking for.

Very comfortable, great fit and durable

I’ve owned one of these bras for several years, and it’s been by far the best sports bra I’ve owned. This is why I just ordered two more (in different colors) for an upcoming week long bike trip. They are comfortable, don’t dig in at the shoulders, give great support, and are reasonably priced compared to the competition. If you air dry them, you can also wear the same bra for at least two days in a row of heavy sweating without worrying about odor.
