Sweaty boobs may cause embarrassment, chafing, and underboob rash. Bra liners are cotton sheets placed under the breasts to absorb sweat. These liners are perfect for those with sensitive skin or who don’t want to use powders or lotions. Below is a list of the best bra liners for sweat.

Best Overall Bra Liner for Sweat: Bamboo & Cotton Liner

This Bamboo & Cotton Liner consists of breathable and pure-cotton padding, keeping you cool in the summer and warm in the winter. Wearing this liner daily enhances comfort across the torso by relieving the bra band and underwire discomfort.

The outer layer of this liner is a blend of soft and silky bamboo and cotton that feels gorgeous against your skin. The inner layer is absorbent and breathable cotton that wicks moisture away from your skin, keeping the region beneath your breasts dry, clean, and free of chafing and pain.

This liner is available in three distinct colors, allowing you to use them beneath almost any bra or item of lingerie. This liner is made from a tagless, soft, and supple bamboo viscose and cotton mix and also features rounded edges for added comfort. 

It also has invisible seams, so you may wear them without drawing attention to yourself. The only drawback about this bra is that it can wrinkle easily, and the fibers can weaken when wet.


  • This liner has a little padding hence making it lighter.
  • It is as comfortable and seamless as the Sweat Wick Liner.


  • When wet, the viscose fibers might become weak.
  • Like the Sweat Wick Liner, which shrinks when washed or when it becomes wet, this one might also shrink when washed.

Best Super Soft Bra Liner for Sweat: Sweat Wick Liner

This Sweat Wick Liner is incredibly comfortable and made of hygienic material. It is made of a bamboo and cotton fiber combination that is extremely soft to the touch. It is significantly softer than cotton or any other type of polyester.

The moisture content of bamboo may be increased by its weight, often due to its capacity to wick and retain the moisture. It has a great reputation for being very soft and absorbing large amounts of moisture without feeling damp.

Also, it is made of a channel-knit, breathable, and stretchy fabric that keeps you warm, unlike the Sweat Wick Liner, which is not stretchy. This liner’s only flaw is that it can shrink in the wash. To avoid this, wash it on a delicate cycle and follow the care instructions on the label.

Finding the ideal moisture-wicking liner requires careful consideration of the fabric from which it is designed. The fabric should be moisture-wicking and comfortable. Cotton does a great job of wicking moisture away from the body and drying quickly when perspiration does escape. KimYoung Cotton Liner is an example of a cotton liner.

Bamboo fiber liners may help you stay dry and comfortable if you want a more efficient and environmentally friendly option. However, this substance may cause skin irritation in certain people. My Bamboo & Cotton Liner is a great all-around option since it is 70% bamboo.

The types of fabrics on the market can help you choose the best liner. Here’s a quick look at the fabric and what it looks like.

  • Cotton is excellent at wicking away sweat
  • Bamboo is all-natural, soft, and airy
  • Nylon is resistant to water
  • Spandex can stretch and bend


Bra liners come in a variety of sizes. Select a liner that complements the size of your bra. Determine your requirements and purchase the appropriate size. Experts advocate measuring across your chest or just dividing your band size in half to discover your optimum size.

Then, choose the liner size that best fits this measurement. To get the greatest fit, ensure the liner isn’t too long and can rest comfortably over your chest. The liner should be snug enough that you don’t have to tug or adjust it during the day. They fit firmly with little chance of sliding down when tucked such that just a small amount appears below the underwire.

How to measure:

  • Just above the elbows and under the breasts, measure the length from under one arm to under the other. This should be about half the size of your bra band.
  • Find the liner size that fits the length the best without being too small or too big. If you’re not sure, round down.

Bra Type

When choosing the best liner for a particular event, you should also consider the bra’s shape and how it will go with your outfit. Take into account the bra you’ll be wearing the liner with. My Bamboo & Cotton Liner is a great all-around option.

You’ll want something a little more classy if you’re mainly wearing dressier bras. If you typically wear sports bras, you’ll want a liner made for them. Nursing liners and strapless liners are also available.

Bras can be made from a wide range of materials. The best bra material for you depends on a few things, like how sensitive your skin is and how much you want to spend. Some of the most common materials for regular bras are:

  • Cotton
  • Rayon
  • Bamboo viscose

Even though each material has its pros and cons, bamboo viscose is quickly becoming everyone’s favorite. The Bamboo & Cotton Liner and the Moisture Wicking Liner are two of my most popular liners, both made from bamboo and viscose.


Bra liners come in a variety of colors. Choose a color that complements your bra. In this manner, the liner will blend in with your bra and not pop out. The color of your liner can also change how your whole outfit looks. Choose from three different color options from my overall liner, the Bamboo & Cotton Liner, which may be worn under almost any bra or piece of clothing.


Before completing your order, check the quality of these detachable liners. Liners should be both comfy and breathable. Look for liners that are lightweight and will remain in place.

Bust Size

Another factor to consider is the size of your bust. You’ll need a more supportive lining if you have a bigger bust. If you have a smaller bust, you may not require as much support and can opt for a lower-weight lining. Remember that most liners are meant for women with smaller busts, so finding one that fits properly may be challenging if you have a wider chest.


Since they can be laundered in a washing machine, liners are suitable for regular usage. To maintain their absorbency, toss them in the washing machine and air-dry them without adding bleach or fabric softener. Also, follow the care instructions found on the label.
