"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."
"This sports bra is comfortable but is not very compressing. It keeps things in place. The band doesn't roll up as far as I noticed. If you have east-west boobs, it's not going to be the most flattering if you were hoping the bra would compress you in at the sides. But it's a very smooth fabric and comfortable for workouts."
"This is a great bra for high impact days. I don’t wear it for walking or yoga or lift days, because it’s just a little overkill for those activities. And for me it’s not an all day bra, I just wear it while at the gym. Perfect for that! Needs to be rinsed after every use for odor. Will probably buy more/again."
"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."
"I love these bras! Clean non toxic fabric and the fit is just right. I hate when sports bras have padding in them that gets all messed up in the washer so I’m a fan of the no padding in this. I like the t back design too. Super flattering"
"I have a pair of the yoga pants that I wear sooo much. They are the softest and best fitting pair I have and I have had a lot over the years. I bought the racerback bra with it and love love it so much I had to buy a second one so I could wash the first one. Knowing that it is safer for me makes me feel good about wearing it while getting sweaty. Thank you!"
"I ordered a few pieces from Definite Articles. In shipping they somehow got stuck in Tennessee, but after a few days, I put in a claim to FedEx and the items were delivered within 24 hours. The only problem was, the Riverline Racerback Bra was missing from the order. I emailed customer service at Definite Articles and they got back to me right away. After explaining what had happened Betrand sent out a new item immediately. I received it within 48 hours. Now that's the kind of company that I will put on repeat. As for their clothing, I was extremely happy to discover how wonderfully they fit and felt while wearing. I haven't washed them yet but I am confident that they will do beautifully. The best thing about the items is that they are not made with toxic materials. And when your skin is a possible pathway for PFAS, this line of clothing seems to be the perfect choice."
"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."
"Great sports bra! I’m a 34D - both fit and support are better than other brands, without the chemicals. The material is comfortable too. I will definitely purchase again!"
"This bra is the best! I love how buttery it feels against my skin and the strong support it provides. I've run with it twice now, and I never once had to readjust. Also, the color is gorgeous!"
