Reviews

Cute but not very functional

"The style is very nice, and the rear pocket for the flask is a great idea. However, it’s very difficult to get the flask in and out. Also, when the flask was empty, it fell out a couple of times, and I had to stop and pick it up. I wouldn’t want that to happen during a race."

— Liliana r. (3/5)

Great bra

"Bought the bra with the matching shorts. I plan to wear this set for my upcoming 50k Trail race this weekend. The bra band is a bit snugger and less stretchy than most bras as stated in previous reviews. The Small still works for me, as I have a small chest and build, but could be too tight if you have a bigger chest or frame. For reference: I'm 5'4 with a 31" chest and 26" waist. I weigh 130."

— Kisha S. (4/5)

Cute bra, but runs small

"I am a petite lady - 5'2'' 110 lbs, size 32b and initially bought a small. WOWEE - it was super tight. Exchanged for a medium just in the nick of time and medium fits perfectly! I can't imagine anyone who would fit into an XS or S who is an adult! Additionally, this is not the most flattering for a bra that will likely be worn in the summer w/o a shirt - it flattens my chest. Lastly, I wish the floral print was small like the matching hat. The big print does not look as visually nice as the smaller one."

— Megan (4/5)

runs small

"same size ordered as others I've purchased and this one is too small along the chest band. Also worth noting is unlike the previous pocket bras, this design makes it harder to retrieve your phone."

— Tatiana G. (4/5)

Attractive new pattern, sizing not good

"I am a very tiny adult (5’ and 94 lb). I can hardly get the small (usually an xs) off after a run, but now it’s too late to return/sold out. Usually I love my Rabbit gear, but this was disappointing."

— Margi J. (3/5)

Runs very small

"I sized up according to the size chart and still couldn’t even get this on. Super disappointed because it’s very cute. This is my first rabbit sports bra purchase, and I’m disappointed! I tried to exchange and the next size is now sold out."

— Meg (2/5)

Love it! Great Bra

"Fits great. Very comfortable, there is a little padding in the straps- nice little feature! Ran 13 miles with the flask in the back - no issues. Love the bra"

— Jamie H. (5/5)

Runs small

"Looks good but runs small. Couldn't even get if on."

— Aveena (2/5)

Game Changer in Hot Weather

"I am loving this sports bra and washing it a lot, and it is holding up remarkably. I put the soft flask in the back pocket, and I am able to hydrate easily on a run. I did utilize the sizing recommendations from the website when purchasing this hydration bra. For reference, in most t-shirts I wear medium. However, I am finding that I wear an XL in many brands' sports bras, and Rabbit is no exception. The XL fits me perfectly, and I have no issues with the band. I highly suggest that you use a cloth measuring tape to measure your chest prior to purchasing, to avoid sizing issues."

— Justine (5/5)

Runs small

"I ordered the same size that I always do in Rabbit and it was so small that I couldn't get it over my rib cage, after barely getting it over my shoulders. It is so cute, but I can't even get it on."

— Steph (2/5)
