Low Impact Bra vs. Medium Impact Bra vs. High Impact Bra

There are so many types of bras nowadays that you could fill your entire closet with a cute collection of bras. But today, we’re here to talk about two bras in particular: regular bras and low impact bras.

While both bras provide support for your breasts while you go about your day, they are built differently. One is for regular activity, and another is for exercising. You see, a low impact bra is actually a kind of sports bra. 

Sports bras hit the world stage in 1977 in conjunction with the women’s lib movement and the booming popularity of jogging. Sports bras are specifically for minimizing the movement of your breasts so that you can exercise as comfortably as possible.

That means the structure they have is going to be a bit different from regular bras. So, make sure to keep reading to get a better understanding of the differences between them so that you can figure out which fits your needs best.

Impact Bras

When it comes to sports bras, there are three different impact levels that they come in: low, medium, and high. What determines the level of impact is the kind of activity the person would ideally perform while wearing it. Then, each impact level will vary on the bra’s structure and the support it provides.

What Are High Impact Bras?

High impact bras are available for people who perform more rigorous activities. This can be anyone like runners, dancers, soccer players, and more. All of these kinds of activities will lead to more breast movement, so brands are intentional about making sure that the bra provides a good mix of support and comfort.

What Are Medium Impact Bras?

Medium level bras are for those whose activity doesn’t result in as much breast movement. Some examples are hiking, golf, etc. This type of sports bra, of course, gives support but with less structure.

What Are Low Impact Bras?

Finally, low impact bras are for any activity that involves minimal movement. Some of the activities people wear low impact bras for are walking, yoga, pilates, and weight training. It’s even great for running errands and relaxing around the house!

If you want a bra that is light and comfortable, then this is a fab option for you.

Best Bras for Everyday Use

When comfort is the name of the game, and you just want a little support in your day-to-day life, low impact bras are high-key the best way to go. 

Let’s get into some of the advantages of sporting a low impact bra:

All-Day Comfort

Wearing a regular bra all day can get so tiring. Sometimes, bras pinch and constrict in the wrong places, especially when you introduce underwire to the equation. Even the straps can cause shoulder pain. But, low impact bras are specifically for comfort.

Low impact bras are usually lightweight, unpadded, and have a stretchy material that lets you feel comfortable moving about without the worry of pinching. Some of these bra variations, like the Peak Low Impact Bra, come with built-in pockets so that you can add padding if you wish.

These bras in such a way that they can deal with minimal movement effectively. The structure in these bras will give light support so that they’re not too tight either.

They’re perfect for lounging around the house, running errands, and going about any of your casual days. When you want the support of a bra, but you don't want to feel like you’re wearing one, this is a perfect option.

Thoughtfully-Engineered Fabrics

One of our favorite aspects of comfy bras, like the low impact variation, is the opportunity to use fabrics that are truly luxe (but also super practical). 

Unlike lingerie that’s more for aesthetic purposes, low impact bras are made with fabric that can hold up to everything from everyday challenges to once-in-a-lifetime adventures. Basically, even when you break a sweat, your bra won’t.

That’s why the low impact bra at TomboyX is made from a unique blend of polyester and Spandex. These fabrics work together to balance stretch and support so that nothing can possibly hold you back from conquering the world (or your shopping list). 

The mesh lining is made from 83% nylon and 17% Spandex. We only use fabric that is OEKO-® certified because the planet needs as much love as we do. 


Low impact bras don’t have to just be for wearing underneath your top. Whether you hit the gym, go out for a pilates class, or just run errands, they provide enough coverage that you can feel comfortable wearing them as a top. 

People wear sports bras so widely now that almost every sportswear brand is coming out with styles that people wear for a bit of a fashion statement. There are unlimited colors, designs, and shapes to choose from.
