Tank tops with built-in support bras (also known as a built-in shelf bras) are great for those days when you want to achieve maximum support with minimal effort, or when layering up feels too constraining. Supported tank tops are built with varying levels of support and different fabric material for all types of exercise – from yoga, to climbing, to trail running, to hiking, to Sunday afternoon chores.
Depending on your breast size and preferred level of support, you may find a specific brand and fabric material works better for you over another. Generally, tank tops with built-in bra support are best for medium impact sports (hiking and backpacking). Although, smaller chested women may find they are perfectly comfortable doing high impact activity in just a built-in support bra.
If you have a larger chest, built-in shelf bras are usually only functional up to medium-impact activity. Those women who are doing more intensive activity or high impact sports will prefer to wear an additional sports bra underneath the supported tank top for maximum support while exercising.
If you can find a built-in support tank top that works best for you, you won’t go back! There is nothing like having an all-in-one experience. And when you are sweaty from a good workout, no peeling back multiple uncomfortable, clingy layers!
Why Go With A Built-in Shelf Bra?
Some tank tops have hidden support sewn into them. The most common type is called shelf bra. Shelf bras are not meant to be worn as the everyday bra. But they sure are comfortable when worn during the right activities!
This two-in-one design is made with an additional layer of fabric sewn into the singlet just below the breasts. The shelf has an elastic that pulls the material tight against the body and helps to comfortably compress the breast tissue in the material. Tank tops with built-in support allow the top to hold better structure and move with your body, rather than getting bunched up under other layers and under your hiking pack.
Most built-in shelf bra tank tops are form fitting or slim fitting. Some have adjustable straps for extra stability and customized support. They can be seamless or will have seams that lay flat against the skin to minimize pressure points against the skin.
Seamless tank tops also allow the material more stretch ability. Most tank tops are made with fabrics and material that make the tank tops naturally lightweight and clingy, but not restrictive. They come in a variety of designs and colors and are fashionable for hiking on the trails and for coffee dates.

Most materials include a blend of two or more of polyester, spandex, nylon or elastane. Additional options include moisture-wicking, ultraviolet protection factor (UPF), and odor reduction.
Moisture-wicking is an important feature. It allows sweat and water to be pulled through the material and away from the body and allowing it to be evaporated resulting in a quick dry function. This helps to better regulate the body’s temperature. Just remember though, cotton is not your friend on the trail. It does not dry quickly and when it gets wet, it gets cold, heavy, and can cause uncomfortable chaffing.
Polyester fabrics have a high resistance to water, wind, and other environmental factors. Although, they are less fire-resistant and can melt easily if ignited.
Nylon is known for being elastic, durable, and dyeable. Pure nylon is not as strong or comfortable as blended nylon proves to be, hence why you find nylon in clothing at lower percentages.
Spandex, also known as lycra or elastane, is a synthetic fiber known for its elasticity. Spandex (an anagram for expands) is known for its elasticity and strength, as it can stretch up to five times its length and then return to its original shape and size.
Most of these materials are made from plastic or coal products and, therefore, are naturally unsustainable. However, there are a handful of responsible companies who make the effort to recycle old materials when making new products. Responsible consumers should also make the earth-friendly conscious effort to support those companies by wearing their recycled or repurposed clothes.

Most brands will provide a sizing chart that can help to better accurately fit their brands sizing to your body. Unfortunately, though, most brands measure their supportive tank tops by generic sizes – XS, S, M, L, XL. Which is not helpful for women’s tank tops where the breast size may not coordinate with your structural size.
It is best to try on tank tops before committing to them. If not, at least read the reviews on the tank tops because reviewers will state their size and body type, explain how the tank top fit on them, and whether they thought the sizing was true to fit or not.
Large or small breasted, most brands have designed functional and trendy supported bra tank tops. It is not longer an article of clothing only appropriate for the trail but is nice enough to wear during day-to-day activities.
Performance in sports and activity can be affected by the type of bra you wear. Exercising or not, a good shelf bra will provide you the proper support to protect and keep your breasts comfortable for long periods of activity. Even low impact activities can cause discomfort if your breasts are not properly held in place. A good quality shelf bra is designed to handle small and large movements.
A regular bra can cause tension on the shoulders, are not breathable, and can create sweat patches that intensify chafing and create rashes.
Breasts are independent external organs that are connected to the body by skin and delicate ligaments. Muscle ligaments in breasts move with body movement – up, down, and sideways. Women have experienced pangs of pain after exercising from unsupported breast movement. Lack of breast support can also lead to back pain.
Even small breast sizes can experience permanent tissue damage. Movement combined with inadequate support will lead to long-term or pre-mature sagging and can cause stretch marks. Once the supportive breast tissues are stretched, they cannot return to the original shape.
Washing your sports bras more often than not is best for them. Washing can mean letting them soak in the shower while you bathe or machine washing them at low temperatures. Air drying is a good option too, as it does not force the cups of shelf bras into positions that can wear down the material faster and leading to a shorter life span.
Be sure to read the label to follow the most appropriate instructions for the particular material of your tank top. It is not suggested to use bleach, softeners, to tumble dry, or to dry on high heat.
