    Finally, a Sports Bra That Balances Real Support with Real Comfort

    I’ve tried a lot of sports bras over the years, and the Momenta Sports Bra from Knix genuinely stands out. It hits that rare balance between strong support and all-day comfort, without feeling restrictive or overbuilt.

    What impressed me most right away was the structure. It offers excellent support, especially for medium to high-impact workouts like running, HIIT, or strength training. Everything feels secure, but not compressed to the point where breathing feels limited. The molded cups give a natural shape rather than flattening, which makes it feel more like a well-designed garment than just workout gear.

    The fabric is another highlight. It’s smooth, breathable, and has just enough stretch. It manages sweat well and doesn’t feel heavy or soaked after a hard session. Even after longer workouts, it stays comfortable and doesn’t cause chafing, which is a common issue with more rigid high-support bras.

    Best sport bras ever

    One of the best sport bras I ever had. Lee everything in place while running or doing hard workouts. Love it and we need more neutral colors.

    Great bra!

    I really am loving this bra so far, I have had it for about a week. I read the previous reviews that said "fits small" so I sized up, which I wish I did not do. I had to do an exchange for the smaller size (which I should have got in the first place based on the website size chart). The online exchange process is very easy! I love the extra material at the bottom of the bra as it hugs against my ribs. I do not spill out the top or sides of the bra. I am large chested and don't have to readjust the bra or the "girls", they stay in place. As this is a medium support bra, I have only worn it as my day to day / lounge bra not to work out in. My only concern is that overtime I am afraid the bra will stretch? I really hope this doesn't happen. I have left it out to dry flat after washing, so hoping as I am following the washing instructions, it does not shrink and does not stretch (or else it will be to big again).

    Finally found a bra that's supportive that I like!!

    I don't like bras and don't like how my bust looks under clothing -- other sports bras either don't provide enough modesty coverage or are unsupportive. This bra is so comfortable I can even sleep in it without feeling constricted or sufficated. Lots of support AND it's (slightly) reductive in appearance! Definitely will buy again every time there's a sale! Love the colors too!
