We've all been there. You want to go for a run, do some yoga, or hike, but you don't have a sports bra that's up to the task. Even worse, your current sports bras leave you with the dreaded uniboob.
If this is a frequent occurrence for you, you're not alone. Many women put up with the uncomfortable and chafe-inducing uniboob phenomenon, especially those of us with bigger busts. Whether you're naturally larger-chested or have had a breast augmentation, you're going to need lots of support during any high-impact activities, but a regular old sports bra won't always do the trick.
No one wants to deal with a sports bra that uncomfortably squishes the bust into a uniboob. So, what can you do to prevent it?
Why Do Sports Bras Cause Uniboob?
Most sports bras are typically compression bras. They press the girls together and hold them still, so we don't have to worry about any mishaps or uncomfortable movements.
Wearing a sports bra that only provides compression can push your breasts together into an uncomfortable heap on your chest. While these bras are designed to hold your breasts in place, the problem is that they don't stop the bounce — they just stop the sway from side to side, not up and down. Wearing the wrong sports bra can cause chafing, excess sweating, and sometimes yeast infections, none of which are pleasant.
Compression sports bras might work for girls on the lower end of the bra alphabet, but the farther up you go, the less useful standard sports bras are. Whether you've had breast implants or are naturally big-busted, you're going to need a full coverage sports bra that ticks all the boxes.
Glamorise sports bras are different from the rest because they provide both compression and encapsulation of the bust. Compression hugs the bust against the body, while encapsulation provides the much-needed separation of the breasts for individual support — which is what prevents uniboob.
Fit Is Everything
If your sports bra leaves your boobs sagging, sides bulging, or leaves you bouncing around when you do a jumping jack, it probably isn't a good fit. A good sports bra will take care of these issues. Before all else, having a proper-fitting sports bra is crucial.
When it comes to sports bras, if you are buying ones in sizes labeled small, medium, or large, you are doing yourself a disservice. All breasts are different — you may even have two differently shaped boobs yourself — which is why a one-size-fits all approach isn't very effective.
You should choose a sports bra that has a specific band and cup size like your everyday bra. When you know your size, you don't have to guess where you might fit on the spectrum, or struggle to slip into a bra that barely fits.
Bras with one-size-fits-most sizing scales are not going to have the best fit, especially for anyone with larger boobs.
Keep Them Separated
Besides being uncomfortable, another obvious problem with uniboob is how it looks. The wrong bra will have your breasts smashed together in an indistinct lump.
When selecting a sports bra, instead of choosing one that lays like a band across the chest to hold the boobs in place, it should have separate cups. As previously mentioned, a good sports bra should provide both compression and encapsulation of the bust. Each boob should be properly cradled in its own personal cup. This design comfortably keeps your boobs in place and avoids creating a uniboob effect.
No matter what size you are, having a bra with both these features is important to combat the dreaded sag and to keep your breasts comfortably supported in every activity.
Closures are Important
Much like with generic fit and proper cup size, the same rules should apply when it comes to the back (or front) of your bra. The back of your bra shouldn't just stretch to fit, and it most certainly should not pull over your head. The right sports bra should hug your curves and give the added bonus of adjustable support.
Having a secure fit gives you the added boost you need, especially while working out. A sports bra with a back hook-and-eye closure with multiple settings will give you a secure fit and allow you to adjust the band as the bra stretches out over time. For this reason, front closure sports bras aren't really that supportive, since there is typically no way to adjust the band.
Cool & Collected
Finally, the last step in selecting the best sports bra to avoid uniboob mishaps is to make sure you get a bra with the right material. Sports bras need to handle high levels of sweat and movement, so picking a sports bra with high quality moisture-wicking fabrics is important. This will ensure your bra keeps its shape longer, as well as keep you dry and cool when you break a sweat.
Materials like cotton may be great for a regular bra, but a sports bra needs to wash well and stay tight. Delicate materials will not do. Plus, you want something that will last and will help you avoid any chafing. With the right material, you can work out as much as you want and avoid the uncomfortable uniboob.
Are There Any Alternative Types of Bras That Can Prevent Uniboob?
Some sports bra styles are better than others for preventing uni-boob. An encapsulation bra that has underwires and molded cups is a great option to prevent uniboob. This sports bra style will keep the bust comfortably in separate cups that not only helps to minimize breast movement, but also helps to keep the bust separate.
Can Adjustable straps Help Prevent Uniboob?
Adjustable straps can help you customize the fit of your sports bra, which in turn may help prevent uniboob. However, adjustable shoulder straps are not a key feature to look for when searching for a sports bra to prevent uni-boob altogether. Rather, look for an encapsulation bra that supports each breast individually, keeping them from rubbing together in the middle of your chest.
What Do Encapsulation Sports Bras Do to Lift and Separate?
Encapsulation sports bras differ from a compression bra in that they keep each breast individually supported in separate cups. Many encapsulation sports bras also feature molded cups which further help to prevent uni-boob. An encapsulation bra is an excellent bra style for both everyday wear and working out.
