This bra says its for high impact, i found this to be untrue.

First off it runs pretty tight. I purchased a 34DD and i read through the reviews and saw mixed reviews on whether or not i should purchase my actual size or not (which is 34DD), and i decided to go with it after reading a few reviews with people the same size as me recommending going with your actual size. For a sports bra, i find that i prefer a tighter bra to hold me in, however if its going to be so tight it's difficult for me to get on (as this one was, i had to seek assistance from my bf for zipping it up) i'd have expected a higher impact resistance bra. I found that i still had a lot more bounce than what i thought i would have and i felt that my boobs spilled out the sides a bit too. I hope that if i wear it enough it'll break in a bit too.

i'd recommend going only one size up.
