How to Size and Fit Padded Bike Underwear

Make sure your Padded Bike Underwear fits correctly to get the protection you need. 

Supporting you and your family to SMILE when you ride.

Welcome.  Understanding how to size & fit padded bike underwear (goUnders) is an important part of your bike riding experience.  Your underwear will only provide you with the protection and comfort they are designed for if you have the right style & size.

Padded Underwear Size 

To get the right size padded bike underwear you must measure.

This is an important part of your online shopping experience.  It’s better to take the time now to measure so you can make more informed decisions. Where you need to measure will depend on the type of bike underwear you are considering buying.  Most will require a hip measurement to be taken.

 

The best way to measure is with a tape measure.  If you don’t have a tape measure use a piece of string or some wool then lay this out along a ruler.

Firstly you will need to find your waist.

To find the natural crease line of your waist, stand straight with hands at the side.  Then bend sideways running the hand down the outside surface of the leg.  This movement will produce a crease at the waist.  Place the top of the tape measure at this crease level.

Your hip measurement is found…  approximately 18cm down from the waist. Let the measuring tape fall down your body to the floor to find the 18cm mark.  Move the measuring tape to this point then wrap it around your body.  Make sure it is straight all the way around.

Putting your padded bike underwear on correctly

Once you have a pair of padded bike undies to try on it is important to put them on correctly, so you can test out whether they will work for your body shape.  This involves getting the chamois in the right place and making sure your waistband is level.

  1. Hold the front & back of the underwear rather than the sides.  This stops the padding (chamois) from sliding backwards and will place your waistband evenly all the way around your body and, therefore, your pad gets well positioned.  Pulling at the sides of your underwear won’t get them in the right position.

Padded Bike Underwear Fit 

WAISTBAND

There are different types of waistbands on different types of padded bike underwear.  We have chosen a knitted 32mm elastic waistband for our brief style goUnders and a slim 6mm elastic for the boyleg style. This waistband should sit evenly all the way around your body.  For the brief style goUnders we have designed two different waist band heights so you should be able to find the solution that best suits your body type.  Please do not position the waistband first when you are putting on your padded underwear.  The chamois is your first point of placement, then the waistband.

Consider the height of the waistband and how it feels

  • Check that the band or elastic is not too tight or pinching in.
  • Is the waistband sitting horizontally?  It should not be higher at the back and it should not be higher at the sides.
  • As you bend forward does the waistband slide too far down your back?

As you go up in sizes the waistband will increase in diameter.

Two waist height options for brief style: mid waist, designed to sit across the top of your hips and high waist designed to sit at or just below your belly button (5cms more height than mid waist). The boyleg goUnders waist sits between these two heights, see photo.Save

CHAMOIS/PADDING

The padding/chamois should feel like it is being held in place, not sliding up your back or hanging/dragging down at the back.  It will feel a little odd between your legs but it should not restrict your movement in any way.  At the front it is designed to protect your pubic bone as you lean or tilt forward on your bike seat.  At the back the chamois is shaped to provide padding & support under your sit bones.  As you put your goUnders on – holding the front and back – you need to pull the chamois as far forward as it will go to get the widest part of the chamois in under your bottom.

The idea is to get the right amount of compression/stretchy tightness in the bike pants fabric to hold the padding (chamois) in place without it being uncomfortable to move.  So do a bit of jiggling around, moving your legs, bending forward, going into a squat position – what does all the moving do to the position of your padding?  It should be held in place.Save

Choose the correct chamois
LEG BAND/HEM

Again it is important that the leg area of your padded bike pants is not too tight.  You should be able to move freely with no restriction or pulling from seams or hems.  Your brief style Padded Bike Underwear has been designed so that the leg hem sits across the crease at the front of your leg – where your leg meets your hip area.  Check that this is where they are sitting at the front.  The back hem should be supporting your bottom, tucked under and covering this area.  The rear hem of your brief style underwear has extra elastic support sewn into it to ensure that your hem is in contact with your skin.

Boy leg goUnders have added length in the hem.  They will sit further down your body and have a 1cm inside thigh measurement.  There is more fabric across the front of your thigh.

Your leg band or hem should not restrict movement.  Check this by moving the part of your body that the band is closest to, that is your upper leg.Save
