Good product

Nice top, gives support for not too dynamic activities. The straps cannot be adjusted. What I don't really like is that it is high on the back of the neck, and after a while it can get annoying. Tiring to remove

Soft cups with the option to add foam padding

The light support fitness bra 100 has soft cups with no padding.You can add foam padding if you want, using the special openings on this model.

A sports bra designed for low-impact activities

The light support fitness bra 100 is ideal for doing low-impact* fitness activities such as stretching or strength training. The support level is especially well suited for small bust sizes.You can add foam padding if you want, using the special openings on this model.*Reduces impacts by 16% compared to a regular bra when doing low-impact activities.

A sports must-have to protect your chest

Your breasts are fragile and supported almost entirely by your skin. When doing a physical activity, they're subjected to much higher forces than in everyday life. These movements and bouncing can create a force of up to five times their actual weight, regardless of your age or cup size. A sports bra provides the support and comfort you need for doing your workout. It protects from impacts, pain and premature sagging.

The right support: neither too much nor too little

The movements of sports activities stretch the skin and ligaments of the bust. Without sufficient support, you may experience pain or premature sagging. But too much support can also be harmful over time: it must be perfectly suited to your cup size and the intensity of your effort. The aim is to protect your bust without altering natural breast movement.

Three levels of support depending on your sport

We have designed our sports bras with three different levels of support to suit the type of activity you do: low support for activities that don't cause your breasts to move around too much (Pilates, stretching, strength training, etc.); medium support for activities that cause a moderate, non-repeated bounce (fitness dance, cardio training, etc.); high support for activities involving intense movement (step, running, trampolining, etc).

How to choose the right bra size

For the best support and comfort, you need a bra that's the right size. To pick the right one, use a tape measure to measure your bust (without wearing a bra). Stand in front of a mirror. Hold your tape measure horizontally at the top of your back towards the bottom of your shoulder blades.Bring the tape measure across the fullest part of your bust. Without pulling it tight, take the measurement.Check this number against the size guide to determine your size.

How are domyos bras designed?

The Domyos sports bras have been created by our team of sportspeople to keep you as comfortable as possible and avoid any health problems. We don't use underwiring because we don't want to risk injuring you or causing cysts by compressing you. We minimise the number of seams around the nipples so that they won't get chafed, and we prioritise fabrics that wick away perspiration in order to keep you comfortable and to considerably reduce the risk of irritation.

How are domyos bras tested?

All our models are verified in our labs using our bust support test, which measures the decrease in acceleration of the breasts during sports*. They are then rated on a scale of 1 to 5: 1 for light support, 3 for medium support and 5 for high support.*The Domyos fitness bras guarantee a decrease in the acceleration of the breasts of at least 10% (level 1) and up to 50% (level 5) compared with a regular bra.

Are decathlon products tested before they're sold?

Yes, of course! All our fabrics must successfully pass rigorous lab tests to ensure your comfort and safety. We check them for durability, colourfastness, resistance to repeated washing, perspiration wicking and more. We call these our ”torture tests”. And after that? Sportspeople like you test the products during their normal activities. We listen to and analyse their feedback to fix what needs to be improved before we bring your outfits to life!

Product testing

This garment has undergone washing and drying tests to ensure that it retains its shape and colour.These tests are regularly performed by an independent laboratory and allow us to ensure that our quality standards are always upheld.We recommend removing the foam padded cups to wash your sports bra.It is best to wash them separately in a net bag.
