I love their binders, I have been using them for about a year now and haven’t found any issues. It is a tad on the expensive side but I find the money worth supporting small businesses and the quality binders. I have a larger chest so it’s hard to find something that flattens me for the most part and this does really well. I find it easy to breathe and the material is really comfortable. I have used my older one of their’s to swim, and while I do suggest going up a size or using a stretched out one for beach activity, it was the absolute best.
