Flex Bra

Choosing the right bra model makes all the difference in the overall look of an outfit and in your comfort throughout the day. The flex bra adapts perfectly to the body, without being tight. It has built-in seams and a wire-free support, avoiding discomfort and marks on the skin.

Insider's bras are developed to provide freedom, safety, and comfort during all activities. To achieve this effect, our underwear is produced with an ultra-soft, light and breathable fabric.

Versatility for the routine

The flex bra was created to be a woman’s best friend in her busy routine, providing comfort and safety. With three strap options, the model is highly adaptable and does not mark the skin, and can be worn with several types of shirts and t-shirts working as an invisible bra.

Besides the strap options, this is a versatile V-neck bra ideal for several situations. Comfort, firmness, and practicality are features that make the flex bra an excellent choice for everyday use.

About our technology

Insider's products are developed with the help of textile technology. With that, we create technological and functional garments. The flex bra contains two layers of technological fabric: the first absorbs the sweat, and the second evaporates it. This mechanism avoids the uncomfortable feeling of dampness throughout the day.

The outer layer is composed of polyamide and elastane, while the inner layer is made of modal and elastane - noble, soft, high-performance fibers. It is anti-sweat, anti-odor, and has antibacterial capacity 75% above cotton. Thus, the fabric prevents the proliferation of odor-causing bacteria.

Comfort and sustainability

Sustainability is part of Insider's DNA, therefore, besides being a comfortable and versatile bra, our product is sustainable. To achieve this result, we use noble fibers and run a production process with low environmental impact.

The fibers that make up the fabric of the flex bra are biodegradable, and the piece can be disposed of in landfills because it will decompose. Furthermore, the production of modal, one of the fabrics used in the garment, uses 4x less water than cotton.

Functional and technological bras

Insider has created a wire-free, highly technological, functional, comfortable, anti-odor, and anti-sweat bra to accompany the woman in her busy routine. This way, we were able to gather the main high-performance features in a single piece.

Besides the Flex bra, we created the Comfy Bra for those who need more support, but do not want to give up the beauty and elegance of this underwear. The comfy is also sustainable and produced with Insider technology.
