Shock Absorber Sports Size Guide
How to choose the right size for you
To find the perfect size for your Shock Absorber bra, it is essential to measure your underbust and bust circumference accurately.
Note: Shock Absorber bras are designed to provide high-performance support, so they fit more snugly than traditional bras.
Step 1/3: Measure the underbust
- Stand up straight and place a measuring tape directly under your bust.
- Make sure the tape is snug.
- Round the measurement to the nearest whole number.
Example: If your measurement is 30 in, round up to 29,5 in. According to the size chart, this corresponds to a 34.
UNDERBUST MEASUREMENT CHART
UNDERBREAST MEASURE (IN) | SIZE |
25,5 - 27 | 30 |
27,5 - 29 | 32 |
29,5 - 31 | 34 |
31,5 - 33 | 36 |
33,5 - 35 | 38 |
35,5 - 37 | 40 |
37,5 - 39 | 42 |
39,5 - 40 | 44 |

Step 2/3: Measure the bust circumference
Place the measuring tape around the fullest part of your bust, at nipple level
Once you have noted your bust measurement, you can proceed to the next step

STEP 3/3: DETERMINE THE CUP SIZE
The cup size is determined by subtracting the underbust measurement from the bust measurement
Example:
Bust measurement: 36 in
Underbust measurement: 30 in
Difference: 6 in → Cup F
Final size: 40F
