You will need a waist & hip measurement to be able to make the best decision about which size is right for your child.

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.

How to find the waist.  To find the natural crease line of a 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 so place your measuring tape on this crease.  Return to standing straight and place the measuring tape around the waist, keeping it even all the way around.

How to find the hips.  Take your second measurement at the hip approximately 9 – 12cm for kids down from the waist (you are looking for the widest part of the body).

See the size charts below to help with choosing the most comfortable size. If your measurement falls between sizes think about what this product is meant to do – hold a chamois in place – so you should go for a size that will be snug.  

Take your time and measure well but be reassured that we love returns because we want you to have the solution that is right for YOU so if you have to send it back it’s no problem at all . See returns

Make sure when you try on your goUnders for the first time you wear some underwear to protect the surface of our chamois.  Once you are happy with the fit it is yours to wear against your skin.  To get the best possible position for your chamois hold your goUnders at the front & back, not the sides as you pull them on
