"I’ve been slowly changing out my workout clothes to brands made without forever chemicals. That’s how I found Definite Articles. I love them! The shorts are soft and stay put. This sports bra is my favorite. It’s also soft and breathable. I live in Hawaii and train in the heat and humidity so breathability is a big deal. I’m so glad I found this brand. I’m going to order two more of this product right now!"
"I am overjoyed with the bra, biker shorts and racer back t shirt I recently purchased and put to the test in the 100 degree hot room. Comfortable, great fitting, moisture wicking and non- toxic is all I can ask for. I will be purchasing more ASAP!"
"I have a relatively slim frame and a large bust and I have never liked many sports bras. I was SO excited to find something that is not only clean materials, but also actually provides great support for high intensity workouts and is comfortable enough to spend the whole day in without giving the uni-boob look. I highly recommend this bra!"
"Can't wait for more colors in these tops!! For is great! Stay in place during hot yoga. . full coverage. . . some other brands are too low and when you bend down its easy for the tops to also go down. . . not the look you want. . . . these stay in place and the material is great Regarding size. . . since wear a large the size is a bit loose in chest. . . but nothing that gaps. . ."
"I got rid of all my older sports bras in favor of more natural or toxin free options. Of the brands I’ve tried so far, this is by far my favorite. I don’t notice it while I’m running which is exactly how a sports bra should be. Fits true to size. I’m planning to buy more."
"Bought my first bra in navy. Loved it so bought another in blaze orange! Super comfortable, nice light support for gym, step class and walking (prob not enough for running). Washes well and did I mention it's ORANGE?! 150 lbs, 5'7" size medium"
"Love this bra! The back is so cute, and it's super high quality. I'm grateful to have found a company that sells high quality, non-toxic workout gear! I'll be back for more."
"I absolutely love these sports bras! I jump for a living as a fitness instructor in our boots in Boston Jumps class and on trampolines. Hands down perfect support and fit."
"I really love these yoga clothes they are my favorite so far they don’t show sweat and yet they are non toxic they also look good after a work out unlike other brands! Thanks !!"
"I love this sports bra! It's incredibly comfortable, supportive, and perfect for Pilates. The fabric is soft, the fit is flattering, and I appreciate that it's made with nontoxic materials. My only wish would be the option for removable cups, but that's just a personal preference. Overall, it's a great-quality sports bra, and I'm really happy with my purchase!"
