Very Supportive!

5 years ago

[This review was collected as part of a promotion.] I ordered a medium in this bra and I think it was just too much support for me. I wear an A-Cup and although the chest strap fits perfectly and is snug and comfortable and is adjustable unfortunately my bust was not able to fill out the padding. I do not usually use padding in my bras and I do not need a lot of support. The padding is none-removable. If you are someone that needs more support than this bra would be AWESOME for ya!!!! Very comfortable and supportive, and super cool design just a little too much support for me! I would be curious to see if I went down a size if that would solve my issue!

Wow - speechless at this product!

4 years ago

[This review was collected as part of a promotion.] I am being totally honest - I was not excited about this bra. I have never found one like this that works. But, I put it on and was obsessed. I cannot believe the way it holds you in. For fun, for 5 minutes my friend and I jumped in place. We couldnt believe the bra comfort and how it holds you in. We were shocked....nice work UA!

So comfortable and supportive!

4 years ago

[This review was collected as part of a promotion.] Love the fit of this bra! Super comfortable and supportive. Love wearing it for high impact and low impact workouts. The straps are adjustable too...I like wearing them as a racerback, but you can also make them straight straps.

Ultra comfortable, perfect support!

4 years ago

Every time UA changes their styles, I wonder if I'll find the perfect sports bra. Then, Yes! The UA INFINITY MID BRA meets all my expectations in terms of breathability, support, rear attachment. The straps do not create tension and there is no friction from seams or uncomfortable underwire. In addition, the straps stay well on the shoulder, regardless of the movements. Suggestion for UA: Offer more choices of pale and neutral colors. For example: white or very light gray which is unfortunately no longer available on the site ... My use: daily, road cycling, sailing, sea kayaking, brisk walking, tai chi.

Love this Bra!

4 years ago

[This review was collected as part of a promotion.] Absolutely love the UA infinity mid level impact sports bra! I'm a 32 DD and have both the small and the medium. I'm on the smallest hook with extra room in the medium and on the largest hook with no extra room in the small bra. I prefer the small over the medium because the support is awesome for high impact workouts like running and HIIT. I'll wear the medium on days I'm not doing cardio and it's very comfortable. I chose to bring my medium for a 7 day, 85 mile backpacking trip. It was perfect and dried fast! I love that the shoulder straps are adjustable as well, and they stay where you set them, even with running. Overall these are very comfortable, I definitely recommend!

Best bra UA has every made, hands down

5 years ago

I absolutely LOVE LOVE LOVEEE this bra. The best feature about this bra would be that it doesn't have removable pads, yet the front has just enough padding built into the fabric to make it supportive, flattering, and you dont "nip" haha. There is nothing more annoying than losing bra pads or having to insert and remove them before and after wash cycles. This is byfar my favorite bra that UA has made, and I have 3 in the high support, 4 in the mid, and 3 in the 3 in the low support. Another great feature is the ability to adjust both the length and the orientation of the straps (crossed or straight).

Stylish and High-Performing

5 years ago

After realizing my current sports bras were over a decade old, I bought several of these in the S (even though the size chart suggested I should be XS) and had to exchange for the XS because there was just too much fabric in the cups. For reference, I’m a 32A. I found them to be a bit tricky to get on at first but I have the hang of it now- pull the straps over your head and push them down over your shoulders, spin the bra to clasp it in the front, then spin it back around again and pull the straps up. Voila! I use these bras for running, spinning, HIIT and yoga and they look and perform great. Can’t speak to their performance with a larger bust size but they definitely work well for me.

Sizing inconsistent!

4 years ago

Really loved the first one I received in pink small. Ordered a small in three different colors and the bands are a half inch shorter than the other one I ordered. Same product name, same design. Returning for 3 mediums but very unhappy with inconsistent sizing! I’m hopeful the mediums will fit in the band and the cups since I should be a small…

Finally a reasonable bra w/ non-removable padding

4 years ago

I landed here after researching sports bras with built-in, non-removable padding with normal/straight straps. I am 5'9" and 170 lb, between a 34 and 36B. I typically wear a large t-shirt and large in sports bras. Checking the fit guide, it recommended a medium for me, but I ended up going with a large since several reviews mentioned it runs really small. At the large, the cup shape is a tad too roomy for me but the straps and band fit well. I'm using this for everyday wear and not high intensity workouts so the large seems fine enough and not worth returning, but I may try a medium in the future. It is pretty full coverage and the padding digs a little into my armpits. The band sits at a nice height, neither causing a fat roll nor rolling up on itself like some bras. The padding creates a natural looking bust, not too protruding or awkward in shape. I am however not a fan of the textured material of the padding, which shows through on a plain shirt (see photo), nor the annoying huge protruding branding text on the straps.

Poor quality control

4 years ago

I ordered the green ones and they came with the front panel sewn in backwards. The lining fabric, a mesh, is on the outside and the matching green fabric is on the inside. Both are like this. I can’t believe no one noticed such an obvious mistake.
