Simple and my favorite Hands down my favorite sports bra. I basically live in them. I wear to yoga, gym, running, lounging - anywhere! I have a couple and wear them often and wash them with care and they still look good as new. You can move easily in it and it keeps you dry. Nice and simple design, will go with anything!

LOVE THIS I am an avid crossfitter and coach and this is my all time favorite bra. Usually wear a 6 or 8 in bras and this one is true to size. I like the cut MUCH better than the energy bra, especially for a more athletic build. I am 5ft 7 138lbs and I have both 6's and 8's. the 6's are just a little tighter but the 8's are more comfortable. March 10, 2015
let down 5'5" 140 muscular build, bought an 8 I bought this bra on recommendation from a friend, sadly, the seam on the sides just below the arm are terribly placed. Additionally, the fit of the bra is very awkward and creates unsightly squeezing near the chest. I wore this bra twice and tried to love it but ended up burying in the back of my bra drawer. Not impressed with this bra. March 3, 2015
Disappointed Over the past year I have purchased this sports bra twice. I find this sports bra to be extremely disappointing. I am a dance instructor and use a sports bra on a daily basis I wanted something that I would feel supported in but I didn't need extreme support. After purchasing this sports bra the first time it completely stretched out. It stretched so much that there was a space between my breastbone and the bottom elastic. Needless to say I loved this sports bra at the beginning so I figured I would repurchase it hoping that the second one might have a stronger elastic. To my disappointment once again I am left with a sports bra that is over stretched and double the size. Do not waste your money on this sports bra! I am a lover of lululemon and always have been, however, I cannot believe how disappointed I am with this product. Sincerely disappointed customer :( February 24, 2015
Awesome while it lasted I am a rock climber and yogi and absolutely loved this bra while it lasted. It felt and looked great under a shirt and it was also flattering and had enough coverage to wear on its own while climbing outside on hot days. Unfortunately it lost its shape really early on. I took it into two Lululemon stores and was told at both that it lost its shape due to wear (isn't that what you're supposed to do with it?). I would have expected more given the reputation that Lululemon has for durability. Despite the short lifetime, it was such a functional bra, I would still buy another one. I really hope that Lululemon will make another bright colored (orange would be awesome!) one soon so I can replace it! February 23, 2015
Disapointed I purchased this bra when I first started doing more yoga. It was comfortable and I loved it so much that I even purchased a second one. I'm disappointed to say that they didn't hold its shape. When I'm moving in class, I find myself worrying about spilling out of the bra. I have not changed in size. For the price of the bra, I figured it would last and I do believe reading somewhere that lululemon gear is supposed to last a few years. In my case, it didn't even last the year. February 17, 2015
Not so great I wanted a sports bra that I could easily slip the shoulder down so I could nurse while wearing it. This bra fits that criteria, but the coverage is all wrong. I don't have very big breasts at all (34A/B), so I should fit into the size 6 according to the size chart. It fits around my body just fine, but even though my boobs are small I feel like I'm *spilling* out of the cups. It's too low, especially the part between your boobs and underarms. The cups are hideously shaped. I fill them out just fine, but they make me look like I have puffy nipples because the middle of the cup is so strange. So that's fine, you can just remove the cups. But with or without them, the bra completely flattens your boobs and seems to push them downward while at the same time forcing them to spill out the top and sides. It's a sports bra, so I wouldn't care about the boob-flattening if it had more coverage (the lack of coverage by the underarms is what bothers me the most, I don't mind a little cleavage at the top). But it's just a super awkward fit, in my opinion. I may try a size 8 to see if my (small) boobs are covered better, but I'm concerned that it will be too big around. I know I can return the bras when they don't fit, but I don't have a functioning printer at the moment, so it's really a hassle. February 10, 2015
Cute but flat boobs I bought this bra on WMTM in the Stained Glass Love Nightfall mostly because I loved the print. The bra itself is just alright. I'm a 36C bra size and I find it flattens and brings down my boobs a bit instead of lifting or staying stationary. If the straps were just a tiny bit thicker and didn't stretch so much I think this bra would be a lot more versatile. It's an everyday bra. I will wear it for around town and light yoga but never for a more intense flow class or to the gym. For smaller chested ladies this bra would probably be good for all activities. For reference I am usually a size 8 in tops, 36C, and 6' tall. February 3, 2015
Well I am so disappointed For years this has been my go to sports bra. Perfect amount of support and coverage for every type of activity: gym, yoga, hiking, you name it! Until last week I had a good supply, but I noticed that a couple of my well worn favs were looking exactly that; well worn! So I headed into lululemon in hopes of getting another couple colors. What I found was that this bra has changed. And NOT for the better. Let me break it down: -I found the material to be thinner and it felt cheaper -the straps have moved in slightly, pushing out that awkward part of skin between boob and underarm (ladies I know you know what I am talking about!) -the shape of the pad inserts changed, creating a very unflattering square boob. If this would have been my first time trying on this bra I NEVER would have bought it. I was so disappointed I wanted to burst into tears. I have been wearing, buying, and promoting this style of bra for the better part of 8 years, and I can truthfully say I am done with it. I left the store without purchasing a thing, and will do some investigation on what other options are out there. I am a yoga teacher, as well as extremely active with out door sports and weight training. Comfort is key. And up until now this sports bra provided me with everything I needed during activity. I sincerely hope that lululemon hasn't fallen behind on their quality, which is why I so faithfully stuck with them for so long. January 28, 2015
My Go To Sports Bra I rececntly cleaned out my closet and threw away all of my sports bras except these ones! I find it to be very confortable and I like that the straps stay hidden under almost any shirt that I wear. I find that it is supportive enough to run in, but I don't have much to support.
