I bought 2 colors in these and I can tell they will be great for hard workouts. The fabric is nice on these and will be cool while you sweat. I also just want to start off by saying, this review is mainly for women who are a size 10 and up who have large chests, small waists, and large bottoms. I didn’t know if I should follow the size chart because I’ve never ordered from Born Primitive before, but I’m very glad I followed it. FOLLOW THE SIZE CHART. I thought I might be able to get a size large in everything I ordered because it’s workout gear and has more give, but do not be fooled! FOLLOW THE SIZE CHART. I really like everything I got and I’m excited to go to our CrossFit gym and try it out. It feels good to be able to wear cute/functional clothes to the gym now that I can fit into them after losing over 100 lbs! For reference I am a 36DDD size 10 and ordered the XL. Hope that helps anyone!
