No seriously, this sports bra is hands down the best sports bra I have ever owned. How much do I love it? This is the 7th one I've purchased and I'm getting ready to order another.So let's just stick this out front and in the open: I'm a short person with huge bosoms. I play a high impact sport and am very active at least 6 hours every week in addition to several more hours of mild to moderate activity. I'm a mother of three that breastfed and the tissue changes show this. Up until this little wonder came into my life I've been relying on a a brand that rhymes with Thunder Farmer to tame the girls. At best I would call that experience "meh," especially compared to this bra. I was actually wearing two, sometimes three different brass at once. In retrospect I was clearly wearing the wrong size- actually, I would say I've been wearing the wrong size since that first awkward trip with my mom to find my first training bra.I digress: if you are relying on what the old lady with the paper tape measure at the big box chain store told you is your size you are probably wearing the wrong size. If you walk into a fitting and they tell you to add four inches, just walk away. This is a big fat lie. Why would you do that? If your band (or underboob, whatever you want to call it) is 30 why would you suddenly and arbitrarily say it's a 34? Once you get that through your head it's a really simple thing to figure out your cup size. Bend over, let the hanging baskets descend in all their glory, measure loosely, and you're done. For UK sizing, my underboob measured 29 (went with 30), the baskets hit 37 inches, so that says I'm a 30FF. Eight inches difference from the original band measurement. Simple. Moving on.In the Thunder Farmer I was wearing a 34DD because that's as big as they get. It never felt like it was as supportive as a high impact sports bra should be but it seemed like it was the best out there. Man, was I wrong. I was skeptical that I was wearing the wrong size, and even more skeptical that this bra would be the magical rainbow unicorn of sports bras. Amazon has been fabulous to work with and the return policy for Prime is more than fair, so I figured I had nothing to lose. A gamble, add to cart, two days later the box arrives, and I tried it on.Just trying it on was a whole other adventure that I won't spoil for other newcomers that are coming to the light from the dark side of vicki's (dirty little) secret. "Is it seriously supposed to be this tight?" "And now I'm supposed to bend over and wiggle everything into the cups HOW?" "But this is a sports bra, why are there two distinct bumps instead of tubeboob?" And my favorite "holy crap, I can see my feet when I look down. Is that what's supposed to happen when the gore actually rests against your skin?" (Note: look up what bra parts are if you don't know what the gore is).Again, I was skeptical, but luckily I had a three hour high intensity event the following morning and felt like it was the perfect time to take it for a test drive. First up: jumping. Let's just say that busty girls do not like jumping. Not even a little. Even if you manage to tame the girls into minor submission you can still feel your breast tissue shifting across the top of your chest, across your pectoralis muscles. After a while you start to feel it in your neck and shoulders, and eventually it creeps all the way into your lower back and ribs. So jump I did, keenly aware that this was a great test of the "86% reduction in bounce" claim. Especially since the breasts were actually separated and not mushed together into the equivalent of wrapping an elastic bandage around your chest. I'm not exaggerating when I saw I felt NOTHING. Not even a little jiggle. Jumped again. and Again. Over and over, and not once did I feel that familiar tug across my chest.Then it was a bunch of lateral agility stuff, then hitting (for the record, I play roller derby). And being hit. After three hours I noticed that I had zero pain associated with bounce and fatigue from trying to compensate for the bounce. I had a serious neck injury a couple years ago so I've been keenly aware of just how much pain the bounce can create in a matter of minutes. Did I say I had zero pain? Because that's a really important detail.Once the event was over I had another event to plan for that night, a full game with a four hour drive. When I got home I took this off. Warning- it takes a couple times wearing it to get used to the difference in how tight the band is in comparison to the poorly fitting band you may have been wearing until then. My skin was a little red where the wires sat, and there were a couple other marks on my back and small ones on the back of my shoulders from where you can clip it together for a racerback style. No biggie. After a quick lunch and clean-up I noticed that two of the three hooks had pulled away from the band rather significantly, and not in a way that I could fix, so I knew I would need to exchange it. Shrugged it off, I had to go, so I put it back on and left it alone for almost seven more hours.Since setting up to exchange with the first one until now I have had no problems with the replacement. I wear this for every single practice, event, work-out, and even the days I'm just going to be moving around a little more than usual. It is honestly the perfect sports bra. I love that it can be easily converted to a racerback style that provides a little bonus lift, and I can disconnect it with one hand. The straps are just the right width. They do not cut or dig into my skin but are not too wide to stick out or sit uncomfortably on my shoulder blades. I do not notice any cutting into my under arms, but it does sit a little higher than I'm used to. The fabric is lined to create support and modesty, but not heavily padded to create shapes that do not occur in nature. The underwires are slightly wider than what I find in everyday-type bras, and this creates a lot more stability in the support I experience.In summary: make sure you're wearing the CORRECT size bra, not what that little old lady told you it was, then give this sports bra a shot if you want great support, great shaping, and comfort. It will take some getting used to but it's worth it. If it didn't look so much like a censor bar I would wear this every. single. day. And if you have a Prime account you have no excuse to not try this. If you've read this far then take my advice and just buy it.Update: I lost a lot of weight after baby #3 and went down two cup sizes. I love this bra so much that I rarely wear any other bra, even for every day wear. If you take care of it by washing correctly and never putting it in the dryer it lasts and lasts and lasts. Of the seven I have one did have a wire poke out under one arm. I simply used moleskin (same kind you use for blisters) over the hole and it's been fine for over a year now. I've added pictures, including one with a thin and tight fitting tank over it so you can see that faint seams can appear with some fabrics. I'm not the fittest person and let's just say I'm no longer in my thirties so it may look like it creates rolls but it does not. That's just how I'm built, it's worse in other bras. The first few hours I wrote this I thought it was a cup size too small but it now fits perfectly. (It looked like there was the chest version of muffin top, I'm not including that picture).
