Hit the roads, trails, or bar
This top is so flattering! It says long bra but it feels more like a crop top. It has a builty in shelf bra made of mesh on the inside. I am pretty small chested so it provides great support for me, but I can imagine it might not for bigger chested folks. The outer layer is made of a slick and sleek technical material, which I love. The cut on the chest is so cute and I honestly think I will wear this running but will also pair it with a cute skirt. I will definitely wear it out to a bar when the pandemic is over. I have a bit of a small waist and love handles so I will probably only wear this with a high waisted bottom because it does accentuate my love handles with low rise bottoms. Feels like run wear, looks like street wear.
Love the phone pocket
I really liked the look of this top/bra. I liked that it had a pocket for a phone. I was specifically looking for this feature. However, I was worried it wasn't going to offer enough support (I'm a 34-36 C). I ordered a medium and small. Once I put the medium on I thought it was perfect. It was snug and felt like it was holding everything in. I liked it so much I wore it around all day. By the end if the day it had loosened up quite a bit. It was perfect for casual wear but too loose for running. Luckily I had the small as well. I put that on and boy it was tight. But once I was running it relaxed to the perfect fit and kept me supported. The only downside is the material on the outside of the bra rides up. So on the model it looks like a long bra/crop top but 5 minutes into the run it rides up to the length of a regular sports bra. No worries though because I bought it for function and not fashion. The phone pocket is perfect for my iPhone 13 and it doesn't bounce around. I will get this in the pink color once it goes on sale.
Exchanged for another brand
The long-line band below my breasts rolled up uncomfortably. I returned the bra and bought a Brooks bra instead
Padding and Fit Comments
Removable Padding, This bra runs a little big. I bought a small and kept the padding in and I went running, I was disappointed that it was not more secure. Recommend buying a size down for running. The design seems like a overall secure bra, but it lacks in reinforcing. It is a rather simple bra design. It is more medium support, not a high support bra.
Light weight
Bought this in a medium. It fits perfectly and I use it more for yoga and climbing. I fear it may not have the support I’d like with my bust size if I decide to run in it. However I love how light the fabric is for sweat wicking.
Definitely not worth $70
If you want any part of your stomach covered do not buy this top, if you have medium to short arms and plan on accessing your phone easily mid run do not buy this top. This shirt constantly rides up so you you have to keep pulling it down if you want coverage. If you don't need much chest support sizing up might fix the ride up problem. The phone pocket is set too far down for me. Trying to fish my phone out is annoying standing still and a huge pain while running, definitely a two hand job. Also heaven forbid you put anything smaller in there like keys, I had to half take the shirt off to fish them out. A popular athleisure brand makes something similar with the phone pocket on the lower back and I like that MUCH better. Otherwise I like the color and fabric. I might buy this again on sale for $20 but definitely not full price.
Comfortable and attractive
I am wide across my shoulders but small chested, so finding the right sports bra is tricky. This Janji Groundwork Long Bra is comfortable under a running top, but also is attractive on its own. This is the second one I have purchased. It has the right amount of light compression I need (AA cup) and the band isn't too tight. I haven't used the between the straps pocket for my phone, because I am not flexible/coordinated enough to get the phone easily out of the pocket, but it does work and I am sure will use it at some point.
Sooo comfortable
This might be the most comfortable bra I have, and gives great support in a variety of outdoor activities. I've worn this for days at a time on bikepacking trips, and it was super comfy on longer hikes over the last month. Feels great worn as its own top or under a base layer, nice versatility! While I'm usually a shirt size S, M worked best in this bra for me.
Love this for running, very comfortable. Fits well, got my usual size (S). I don't find that it tends to roll up too much like some shirts of this style.
Janji for the win!
Looks great! Love Janji! I think this will work well for my race.
