How to Measure for the Correct Size
High & Mid Waist Bike goUnders are a fitted bike underwear (they stretch to fit firmly but comfortably onto your body). For this reason our sizing may be different to your normal underwear size… so please measure.
To get the right size you need to know your waist & hip measurements.
WAIST MEASUREMENTÂ
Find the natural crease line of your waist.
Stand straight with your hands at the side. Bend sideways running the hand down the outside surface of the leg.  This movement will produce a crease at the waist
Return to standing and wrap the measuring tape horizontally around your body at this crease line.
HIP MEASUREMENT
Measure approximately 18cm down from the waist
From where you took your waist measurement let the measuring tape hang down the length of your body.
At 18cm down wrap the tape horizontally around your body.
Measure for Brief Style
Tips for Measuring
- Use a flexible measuring tape (if you don’t have a measuring tape use string and then lay the string along a ruler to find your measurement).
- For an accurate measurement
- the measuring tape should sit snug next to your skin.
- do not measure over bulky clothing.
- make sure the tape is level around your body… to achieve this, get help or measure in front of a mirror.

Common Questions
I measure between sizes.
We would recommend the larger size. The fabric of Bike goUnders provides a good amount of stretch and compression. The larger size will be more comfortable to wear and still provide the firmness needed to hold the padding (chamois) in place.Â
My hip & waist measurements are different sizes.
Bike goUnders are designed to be a firm fit to hold the padding next to your body. We recommend being lead by your hip measurement as this is the area where you need the best fit.
If your waist measurement is significantly larger than your hip measurement (body shape is described as being an apple) please consider our Boyleg style. Apple body shapes are a much better match to the Boyleg design.
