This bra is really comfortable. The fabric is thin, mesh-like, and does dry very quickly. Making the bra fast-drying meant sacrificing the ability to add support. This was fine for me in non-impact sports, but those requiring a larger cup size (for reference, I ordered a 32B) may need to check for fit or even order a size down to keep it snug. I haven't tried it with high-impact activities like running.
