Measuring Tips

Here are some tips to help you order the correct size. If you don't have a measuring tape, use a piece of string and hold it alongside a ruler.

Waist

Measure around the narrowest part of his natural waist. To ensure a comfortable fit, do not pull the measuring tape too tightly.

Inseam

With no shoes on, measure from the top of his inner thigh down to the floor.
