- Low support (yoga, stretching, muscle strengthening, etc.) for activities where the breasts will not move much.
- Medium support (fitness dancing, cardio training, etc.) for moderate, non-repeated bouncing.
- High support (step, running, trampolining, etc.) for activities involving intensive movements.

The right size ensures good support and a comfortable fit.
To figure out your bra size, take your bust measurement:
* Measure yourself without a bra on.
* Use 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.
You can then check this measurement against the size chart.

Our models are designed to increase comfort and help prevent health problems:
* we do not use underwiring (risk of injury and compression of the lymph nodes)
* we minimise seams near the nipple (to prevent chafing)
* we use components that wick perspiration away from the body (improves the level of comfort and considerably lowers the risk of chafing).

All our models are verified in our labs using our bust support test (measures the decrease in acceleration of the breasts during sports).
They are rated and categorised:
1 : light support
3: medium support
5: superior support
* Our fitness bras guarantee a reduction in the acceleration of the bust compared with a standard bra. 10% minimum (level 1) up to over 50% (level 5).

A product's environmental impact is calculated for its entire life cycle using various indicators. An overall rating (ABCDE) is given, allowing you to easily identify products with the best environmental performance by comparing similar products to each other (T-shirts, bottoms, backpacks etc.).
Decathlon openly displays the environmental ratings of its products. Find out more: http://sustainability.decathlon.com/
