"Good fabric and color! I had to size down from a small to xsmall to get the high impact support fit I wanted. Other than a little more side boob or uniboob action to get the support, it been working great. Very smooth feel. Looks clean, not unnecessary extras like mesh, ribbing, seams, etc."
"Great compression and support with a very comfortable fit. I’m a 32D and purchased a Medium and it fits perfectly. I wear it for Pure Barre and feel confident in bending, stretching, and hopping in it. The material feels like it will last. I choose to hang dry after washing on cold with dark colors. It’s black and is showing no wear or fading after a month of washes."
"Love this sports bra! I have 3 of the colors and hope to get a couple more. The material is high quality and stretchy. They are great for high impact. I chose to size down so that it held me in a bit more. I'm 5'6" 150 lbs and 34c and the small worked for me. I love that they are full coverage as well."
"I love everything about this sports bra! It fits perfectly, is super comfortable, supportive, and I really appreciate that it doesn’t have padding. For reference, I’m a 34D and ordered a medium."
"I am a holistic and integrative medicine provider and care about the material I have against my skin. I love definite articles! The fit it’s always perfect and so comfortable, without my skin absorbing toxins."
"I love this bra! The fit is comfortable, flattering and functional for my training. It is a bra I could wear all day. I am usually between a small and a medium so I ordered a medium and it was too big. I exchanged for a small and it’s perfect. Will be ordering in more and would love to see a wider range of colors!"
"I am a runner and wondered how supportive this bra would be for me. I feel like it is the perfect support for my 32c."
"Love the material and the fit. It feels more supportive than other brands I’ve previously worn. So happy I’ve found a healthier brand that has an elevated quality and style!"
"Fit is perfect, feel is great, comfort is everything I want. Customer support went above and beyond to ensure I was happy. I'll be happy to order from this company again."
"This is a fantastic bra. I don't dread workouts anymore because I feel supported and I don't have to worry about PFAS and endocrine disruptors. . . just good old fashioned sweat. 😉"
