This bra is the wrong size for me, so I'm not entirely sure how it would fit in the correct size, at some point I'll buy a 34FF that I need. It is a really comfortable, nicely shaped, supportive bra. The J-hook adds extra support when needed, and the encapsulation cups do a nice job of keeping everything in place.
Feels nice, the best sports bra I own. I got it in a sister size (36E instead of 34F) mostly because it felt okay and Nordstrom Rack didn't have a 34F to try on. It seems like the band in this bra is tight, though, so it was probably a good move. Tight bands don't make my asthmatic lungs feel very nice during cardio.
The true test will be when I actually wear it to the gym, which I haven't done yet.
