    My favorite Knix bra!

    This is my favorite Knix bra! It has excellent support for my breast and light support for my upper back due to the heaviness of my breasts.

    This Sports Bra is exactly what I have been looking for!

    Not only does it offer great comfortable support, it is breathable & is the bra straps are never seen, even in sporty raceback tank tops.

    Supportive and Comfy

    I’ve tried a lot of sports bras over the years, but this one really stands out. The fabric is soft and breathable, so it feels great against the skin and doesn’t dig in anywhere. Even during longer workouts, it stays comfortable without that “suffocating” feeling some bras give.

    The support is impressive—I feel secure whether I’m running, lifting, or in a high-intensity class. The straps stay put without slipping, and the band holds snugly without being too tight. I also appreciate that it gives shape and lift without adding bulk.

    What really sets it apart is the balance between support and comfort. Usually, I find bras are either one or the other, but this feels like the perfect middle ground. I could easily wear it for everyday activities as well as workouts.

    Highly recommend for anyone looking for a sports bra that’s reliable, flattering, and genuinely comfortable.

    Incredible!

    I RARELY leave reviews, but wanted to say how great my experience was with this sports bra. I hate sports bras and can usually tolerate them for no longer than a 30-minute workout, but wore Knix sports bras (including this one) all day, every day over a month-long, 500-mile hike and found them incredibly comfortable. Supportive without being restrictive, wicking, easy to wash - excellent products!!

    I need the olive color restocked.

    This bra is perfect support and has the best size range I've found anywhere. I purchased this bra a couple months ago and now I lost weight and need the L++ in olive! Please restock this color!

    Good fit for waistband but bust seems too small. Bought according to size guide but should have gone with L++.

    Lost elasticity

    I bought 2 of these bras 6 months ago. For about the last couple of months I've noticed they don't have support anymore. Within an hour of putting it on my boobs will be falling out of the bottom of the bra ... literally. I would think given the cost, this bra would last longer than 4-6 months. Or it's just not made for larger sizes...I bought size L and L+. Really disappointed
