Great for high impact exercise!

I bought these bras after careful research because I was shipping to basic training for the Army and obviously needed a sports bra. At the time I was a 34 D-DD. I bought 4 of them total to the tune of ~$160 total, and while in BCT I wore the same 4 of these 6 days a week, 24 hours a day (no exercise on Sundays, so I wore one that they made us buy that was far less supportive). I had absolutely no problems with chaffing despite the fact that it was on average 90 degrees each day and we sweat from sun-up to sundown. The bra is adjustable thanks to the bra-type closure on the back and the adjustable shoulder straps to loosen or tighten. I never had a problem with my chest bouncing all over while running or hiking. They stood up to getting washed 2x a week or so without a problem. I bought a 34C size since I knew would lose weight so I just wore the bra with the back closure all the way out and the straps looser to start and I still had no problem. I lost enough weight that I shrunk down to a 34C and they still fit no problem-no stretching out or anything. I got injured 7 weeks into BCT and had to go to another unit where we did exercise every day, just less intense. That was in October and I just got home at the end of March. From September to March I wore these bras every day without issue, and now that I'm home I still use them to workout as they haven't broken down any. The initial cost sucks but every penny was well worth it.
