Sisters Bra

Inspired by the engineering of suspension bridges, the Sisters Bra is designed for maximum security, support, and coverage at all points. The name alludes to the sisterhood in its design: two layers of construction working in harmony. An inner layer, which includes unique meshes and molded cups, while attaching those elements to an inner set of straps. This inner layer = encapsulation, supporting each breast. The outer layer and outer straps represent the compression, holding everything in place. The four-strap system more evenly distributes the weight, relieving strap pressure which can often cause pain or welting in the skin. The Sisters Bra is also higher on the neck, to minimize top bounce, with the two layers of mesh at the neck serving both form and function. Learn more about the Sisters Bra on the blog.

Great Bra for DDs

I didn't want to risk buying yet another sports bra only to find it wasn't supportive enough. I waited for a sale on the bra and then I bought it. I was very pleasantly surprised! I has great support for running! There is still some bounce, but the bra is very comfortable. (I usually wear the Shefit Flex bra which is not as comfortable as Sisters.) I also like how the bra comes up higher to cover cleavage. I did buy a size down (D) and this fits snugger but I am unable to tie the back without help -- but I am keeping this bra too. I have been wearing the bra for a few weeks now for running, and just really like it. Still a little in shock that this bra is as good as it is.

Finally a Juno replacement!

I have bigger boobs and was devastated when Brooks did away with the Juno then I found the sisters bra and it’s wonderful! It is actually better than the Juno. No chaffing and better coverage/support!

If you loved the Juno, try this!

I wore the Brooks Juno and Rebound Racer exclusively for the past 8 years. I was very bummed with the new Brooks line - I am a 32DD and I really feel like they made the new Run Bra line beautiful, but they DID NOT build bras to support bigger boobs. This bra is a VERY GOOD replacement if you have bigger boobs and need a high impact bra. Just like the Juno, it's kind of a workout to put on, but then everything stays put and the band is super supportive. I'm a little worried that coverage is so good on the side boob that it might chafe on long runs - that's my only reservation on fit. I really wish Oiselle could bring down the price (the old Juno was closer to $60) and I don't think bigger boobs should have to pay the price for support. Please, Oiselle - equalize the price on sports bras and I'll be happy!
