Notes

Chest - Measure fullest circumference, keeping tape up under arms and around shoulder blades.
Waist - Measure at narrowest circumference.
Height - Stand with back straight; measure from highest point on head to floor.
Inseam - Measure inner leg from crotch to ankle bone.
Length - Measure from adams apple down towards the crotch.

We recommend that you match your child's height and weight to the chart and then choose the next size UP. This will generally give your child two (2) seasons with the same item. For example, a 3 year old may likely be best suited to a size 6, particularly if he or she is a large 3 year old. A size 6 may also be suitable for a 4 year old.

The sizing chart displays dimensions that are designed to fit the particular size, therefore they are not the actual size. For example, I am a 46 yr old male with a 44" chest, and find that a 3XL is more relaxed & comfortable, however, a younger male might prefer a more snug fit and may prefer then to go with a 2XL.

Notes

Inseam - Measure inner leg from crotch to ankle bone.
Length - Measure from your adams apple down just below waist.

The sizing chart displays dimensions that are designed to fit the particular size, therefore they are not the actual size. For example, I am a middle aged male with a 44" chest and 38" waist and find that a 2XL is more relaxed & comfortable, however, a younger male might prefer a more snug fit and may prefer then to go with a XL.
